I noticed that the actual render resolution of the HMD when running VorpX isn’t that high now that I’m running a MeganeX 8K… any way to make it higher?
I’m used to play games now at around 5000×5000 to 7000×7000 and VorpX seems to run at like… 2600×2600 I get the impression? So even when I run the game at those high resolutions, the image quality is substantially lower than it should since the panels on the MeganeX are close to 4000×4000 by themselves already.
It is especially noticeable in Desktop mode, or with some specific games that I can run in UEVR at 7000×7000 and get flawless image where pixels are effectively invisible, but on VorpX is somehow greatly diminished by this issue…
You probably have a good sight and are probably very sensitive to PPD (you bought a 8k VR headset so it’s not surprising ;) )
Maybe there was a limit in order to optimize ?
I wonder how you can use this kind of resolutions in VorpX. We probably don’t play the same games… (Frontier Of Pandora, Metro Exodus, Atomic Heart, etc.)
Or you have a lot better graphic card.How do you do ? Virtual Monitor is limited to 4860p as far as I know (I never tried above 3840p because I mainly play recent AAA games and even with an RTX4090 it would be hard to keep a decent framerate. I don’t know if it would be useful to me. In my opinion, 2880p is enough with a lot of old games because of textures limit, even if VorpX enhances them a lot).
Besides, I think I prefer my G2 (2160p) over my Varjo Aero (2880p but maybe there is more pixel density at the center of the fresnel lenses), and the G2 ratio is probably closer to my field of view, the way I wear these VR headsets, so I can see more details in full VR with the G2.
Curiously, I can also see more clearly the pixels on the Aero (maybe because the G2 is afocal and my sight is almost but not completely 10/10). Sometimes it’s not so good to see too clearly (but anyway I don’t concentrate on pixels during playthrough).
So I don’t think I could really see the difference, especially in game, between a 4000p VR headset and my G2. Anyway it’s still way better than a Quest 3 at medium/long distance ;)
The most important thing is the displayed image in my opinion.
Even if my Reverb G2 is 2160p and even if my sight isn’t 10/10, I can clearly see :
– the difference between 2880p, 3200p and even 3840p game resolution (but only in very recent games because as I explained it doesn’t really matter in old ones). It seems most games arent really perfect at a given resolution. You have to render them in a higher one than the displayed one.
– the difference between VorpX and UEVR clarity and sharpness.UEVR’s sharpness & clarity isn’t even close to VorpX at medium/long distance in every AAA game with large outdoors environement I tried (even with 6000p resolution in UEVR, it’s still blurry at medium/long distance while VorpX is usually great even in 2880p). The fact I usually can use a wider FOV in VorpX may play a role but It doesn’t explain everything.
Of course VorpX handles more optimized game engines than UEVR, but even with Unreal Engine 4 VorpX is always a lot better in this case (didn’t really compare UE5 yet). I haven’t found a way to fix it yet, and I don’t think there is. I asked around me and everyone confirmed this phenomena, even on Pimax Crystal Light. It may depend on the technologies used by each game I suppose.
UEVR’s sharpness & clarity isn’t even close to VorpX at medium/long distance in every AAA game with large outdoors environement I tried
This is SO WEIRD to me.
Because its the literal opposite to me in 100% of the cases.
UEVR is always sharp to perfection (even if my GPU wants to cry at single digit FPS) when I crank up resolution, while no matter how high I put the resolution on any VorpX game… it always looks “terrible” (at around 2000-ish p). Like, I can put the game at literally 8K (4000p), the GPU is clearly doing it, since the game chugs like it wants to die… yet the resolution and jaggies I see are identical to the ones I had when rendering the game at 4k (2160p). That’s the issue for me there. Hopefully that explains it better!Also, to my knowledge… UEVR is best in UE games overall, by a lot. And I mean, its not surprising really, VorpX works on like a bizillion other engines, while that one is specific to UE4-5.
An example of that would be Harvestella. I can run the thing on UEVR at 15000×7500 (yes, 7500p per eye), at around 30-45fps. It uses up every ounce the MeganeX8K’s clarity, literally can’t look better. Then when I try to run it at 8k (7600×4300), it really doesn’t look any different from just playing it at 3860×2160.
So something weird is going on on VorpX that is limiting the resolution it renders at.
The Desktop Viewer itself, looks poor compared to the image that the SteamVR UI window gives too. Maybe running at high 2000p? But basically unusable compared to just using native SteamVR desktop windows…PS. I have around 20/20 vision. With the MeganeX8K you can actually do the optometrist tests and pass them about as well as you would in real life, it is just that dense in pixels. The difference between 2000p and 4000p is about the same that you notice on a 1440p to a 4K display, so its quite noticeable to me.
Also, to my knowledge… UEVR is best in UE games overall, by a lot. And I mean, its not surprising really, VorpX works on like a bizillion other engines, while that one is specific to UE4-5.
UEVR doesn’t even handle raytracing in UE4 games and it has a lot of visual issues (animations glitches, camera clipping, 3D and camera doesn’t feel right in first person games, etc.)
Stability can be bad (it often crashes) and it’s not reliable, at least on my VR headset.
It’s most of the time unusable if you want your PC to remain silent (even with a very expansive one).
It’s definitely not better than VorpX. At best it’s different, but image quality can’t even compare because most beautiful settings don’t even work with UEVR.
And VorpX is so much optimized than it’s a lot better with AAA games on current graphic cards.
I agree UEVR can be a lot better in some minor games with little environments when VorpX has no profile because you can get G3D and image quality is good at short distance.
How do you configure UEVR to get a good image quality and see every details miles around like in VorpX ? Because every person who really tried both around me said me that VorpX has a lot better image quality.
Maybe you don’t know how to configure VorpX, or as I said, you are very sensitive to something most people don’t even notice.
Or maybe there is a compatibility problem with your uncommon VR headset or as you said a limit to PPD somewhere, which doesn’t concern most people and has probably no real effect on most recent games.Did you try the ClarityFX, Sharpness and Texture Enhancements settings ? (VorpX’s Ingame menu page 2) It’s very impressive on my VR headset if properly configured.
Some people use OpenXR toolkit to improve image quality but I didn’t need it.Most people really don’t need this level of details anyway. I’m pretty sure there is no way to reach VorpX’s image quality with UEVR in an AAA game (or I don’t know how to do it, and no one arround me found out).
We probably don’t play the same games. I mostly play AAA games in VR (and anyway most of them aren’t made with Unreal Engine, except Atomic Heart which is an UE4 game and is better in VorpX).
As far as I know, you can always use max settings with VorpX in AAA games with a good enough resolution. It’s impossible with UEVR (either because it doesn’t even work, or because it works but it’s not optimized enough).
As I said, you could not reach such resolutions with most beautiful games (especially with Unreal Engine 4/5 AAA games…)
So It depends on the game, and on your use. Anyway both programs have other pros and cons depending on your expectations.
It’s definitely not better than VorpX. At best it’s different, but image quality can’t even compare because most beautiful settings don’t even work with UEVR.
I see! Maybe it varies a lot between games, because the games that have proper Native Stereo for me… look like the improved version of the monitor version. And I’m a graphics whore, after all, I’m a professional 3D videogame artist.
How do you configure UEVR to get a good image quality and see every details miles around like in VorpX ? Because every person who really tried both around me said me that VorpX has a lot better image quality.
I’m… not sure. I’ve been using VorpX since the early days, even going as far to using the shader authoring tool to create my custom profiles and… Even if its good, its never been flawless as UEVR seems to get to. (although I get way less control in UEVR without actually coding in LUA than with the authoring tool :S)
Well, let’s put an example. If I run Tales of Arise on VorpX, a UE4 game. 3D shadows are borked, due to the common issue with shaders on G3D. On top of that, like I said, it not only runs in a “window” since it isn’t fullVR compatible, but even when put both in that mode, VorpX only goes as high as under 3000p. On UEVR most shaders are flawless, except for the camera FOV that seems a bit weird at times (since it doesn’t zoom in like it would in a 2D screen)… and that’s it. I can run it if I can at 7000p, where pixels are literally so small I can’t tell them apart. A visual clarity that is so ridiculous I can see into the distance (at like… 10fps, of course lol). But even in UEVR “2D window” mode, I can easily put it at 5000p, get 90fps, and flawless image.
Maybe you don’t know how to configure VorpX, or as I said, you are very sensitive to something most people don’t even notice.
Maybe I’m missing something, but I mean, like I said, been using the thing since the early days, and I’m a user advanced enough to make their own profiles with the authoring tool… Tinkering with settings is totally my jam.
I just think not that many people are running HMDs with resolutions of 3550×3880 per eye yet. It would be ideal if Ralf could throw some light into this to be honest! And I mean, many people would notice if a program is rendering at like 2/3 or less resolution the HMD is capable of, I’m sure!Did you try the ClarityFX, Sharpness and Texture Enhancements settings ? (VorpX’s Ingame menu page 2) It’s very impressive on my VR headset if properly configured.
Yes, of course! I mean, it does make things better, but that doesn’t cut it, it really just needs way more resolution.
We probably don’t play the same games. I mostly play AAA games in VR (and anyway most of them aren’t made with Unreal Engine, except Atomic Heart which is an UE4 game and is better in VorpX).
I see! Surely we don’t play similar. To be honest, I like VorpX better as a “3D window” to the world better than full VR immersion. For that I feel UEVR is great, since it basically uses native UE VR rendering pipeline to show stuff.
As far as I know, you can always use max settings with VorpX in AAA games with a good enough resolution. It’s impossible with UEVR (either because it doesn’t even work, or because it works but it’s not optimized enough).
The problem is I straight out can’t. Like I said, is like VorpX just hits a ceiling of resolution the HMD won’t go over, even when I’m trying to force it (be it through the game engine rendering at higher resolutions, or the settings in SteamVR).
As I said, you could not reach such resolutions with most beautiful games (especially with Unreal Engine 4/5 AAA games…)
I mean… I have a heavily overclocked 4090 with a 9950X3D, and tolerance for low FPS, so I can easily play a game at like… 40fps and not feel wrong about it. Even in VR I play with most maxed out always (when it makes sense ofc). I don’t play that many AAA games though, I’m more interested in AA and indie, with the nice AAA here an there.
So It depends on the game, and on your use. Anyway both programs have other pros and cons depending on your expectations.
Yeah! I just seem to choose UEVR for all the UE games.
Hopefully, I am doing something wrong, or there is a fix I didn’t think for this! It really is a shame not being able to use VorpX now that the MeganeX8K is giving me such ridiculously high PPD (it sits at around 46PPD, with mOLED quality, its insane!)
I made some screenshots on both programs. UEVR is running in 2D screen mode to emulate how VorpX does in order to make the comparison fair. I kept the images as close as possible. Hopefully it will help!
I got the screens as close as possible and it 100% proves my point.
UEVR is rendering at a way higher resolution, even when both are “at 4860p”Notice how in the UEVR one, even when the camera is positioned further back (which should make the jaggies worse), its still miles ahead of it!
Good places to check resolution:
-Big letters at the top
-Protagonist’s hairThe worst is… these images are actually FLATTERING to VorpX. It looks SO MUCH WORSE when in the HMD… the images are “only” 2300p after all, and you aren’t being blinded in one eye due to the bad G3D shadows (but this is besides the point).
Reminder that this isn’t a game specific issue. It is happening with everything, including VorpX Desktop.
@Ralf
Any idea what might be at play here? I tried V21, V23 and V24, all of them showing the same issue.Mmmm…
Both images look terrible in your pictures.
It’s always possible to get a lot better image than that, at least in VorpX (UEVR isn’t even close in most games I tried).
It can be a profile or configuration problem (maybe the wrong type of 3D, etc.)
Or maybe it’s the game ?
When I use VorpX in a game like Bioshock 2, Metro Exodus or Frontier Of Pandora (or Hogwarts Legacy / Atomic Heart if you want UE4), the image quality is far better than any real 8k video I could record myself.
This is worse.
This is ugly even in 1080p. You shouldn’t be able to notice it on a 1080p monitor (impossible).
If the image quality is so bad, I guess it’s because you weren’t able to record correctly the output ? In this case I don’t see how we could compare.
Anyway, if you play AA games with UEVR and no good VorpX profiles, UEVR has a lot of qualities, especially if you don’t really care about immersion and full VR, and just want 3D, and especially if you prefer G3D over image quality and if your computer is powerful and silent enough. Maybe you can use VRto3D in this case.
Why do you want to use VorpX instead ?
VorpX is great to play AAA games in full VR (or Immersive Screen) with the best graphics available. Especially First Person games (if you want a perfect native-like experience). You don’t really need it to play AA third person or strategy games based on Unreal Engine 4/5 (even if it should work a lot better than that).
I’m also a professionnal game developper (and I have advanced 3D modeling, animation and rendering skills too but it doesn’t really matter).
There is no way I can see blurry letters in VorpX.
But as we said, you may be right on a PPD limit. I wouldn’t be able to tell with my current VR headset, which is already better than most.
I never use auto resolution, but most peope do, and as far as I know it limits resolution (it depends on game profiles).
Make sure you disable it if you want to play in very high resolution.
With the extreme resolutions you are mentioning, I think only the virtual monitor can reach, although it might currently be limited to 4860p max in the vorpX app.
Are you turning off your physical monitor when playing? Or rather, does vorpX turn off your monitor? This is how you know the virtual monitor is active.
If your physical monitor is active for playing, you may be limited to its capability.
In my experience, standard 2D games can only be set to render as high as your monitor can accept. In the case of my physical 1440p monitor, 2880p is the highest custom resolution test it can pass and create. Therefore 2880p is the highest in game resolution I can select in game.
If I want to go higher, I must use vorpX’s virtual monitor instead. I use the vorpX app to create and save the custom resolution I want for the virtual monitor, then select that resolution within the game’s settings.
It’s important to note that you must have these custom resolutions created for a game to be able to recognize and display them. You test and create these in Nvidia Control Panel for your physical monitor, or the vorpX config app for the virtual monitor.
Forgive me if you already knew all this. I only mention this on the chance you are skipping something. like editing a game’s ini resolution without first creating the monitor custom res to match.
It’s the in game selected resolution that matters, not the SteamVR slider.
And don’t use the Desktop Viewer (not to be confused with the Virtual Monitor) for games, always better to hook in with vorpX the intended way. Even for 2D play. The viewer is just capturing the desktop, performs worse, and looks pixilated.
Most of the time, it’s not complicated if you use the virtual monitor (launch Desktop Viewer before hooking) : if the game isn’t restrictive, you just have to modify the game resolution in the game’s video settings.
With Bioshock Infinite, you don’t even need the virtual monitor because the game accept any resolution/ratio you want if you play windowed (but it’s still better if you want to play fullscreen in order to avoid mouse limitations in the main menu).
In addition : some unusual games use physical monitor’s resolution when they are in full screen mode (like Metro 2033 original). In this case you have to specify the windowed mode (in the .cfg file of the game or in the game’s video settings). With this particular game, the window must in addition not be larger than the destkop (you can guess why), so you must actually modify the virtual monitor’s desktop resolution with Windows display settings.
There may be be other special cases.
—–
I wouldn’t say the viewer automatically look pixilated if properly configured in immersive screen (at least without 3D). I didn’t really compare but it can be very good (at least the way I use it : high FOV, high resolution, low distance and high curvature, so a curved screen larger than my field of view). I think it’s simply more important to choose the appropriate resolution with the desktop viewer. But it may depend on a lot of things (VR headset, settings, etc.)
—-
Anyway, with hooked games, if you don’t see any difference between resolutions above 1440p or 2160p (or even 3200p), there is a problem somewhere, because it’s not the usual behavior.
It may be because of the game or the profile.
I never use VorpX as a distant 2D screen (except with edgepeek during cutscenes&menus but not so distant). Maybe it’s because you don’t use it in an “immersive” or VR mode.
Everytime I tried, UEVR was particularly bad in 2D screen mode (a lot of aliasing and there is no curvature so there are distortions).
It’s not really relevant in my opinion to compare both programs in their worse modes/configuration (which I would never use haha).
Anyway I mainly use VR mode (or immersive screen) with both programs and VorpX always had a better image quality in large environments.
Both images look terrible in your pictures.
Well, they are raw images 2k images downscaled from almost 5000×5000 resolution output.
The UEVR looks worse (since its actually rendering at 4860p), the VorpX one… actually looks better than on the HMD.It can be a profile or configuration problem (maybe the wrong type of 3D, etc.)
It is in all games, in all types, from flat 2D to geo3D and any normal configuration.
Its like if VorpX internal resolution has an arbitrary ceiling it won’t go past for some reason.This is ugly even in 1080p. You shouldn’t be able to notice it on a 1080p monitor
Yeah, the image quality of VorpX is only SLIGHTLY better than on my VivePro… which has SIX times less pixels than my current HMD…
If the image quality is so bad, I guess it’s because you weren’t able to record correctly the output ? In this case I don’t see how we could compare.
I exported the raw output, that way they are comparable, its what its being fed to the HMDs.
I tried to take regular screenshots, but UEVR in 2D mode won’t play ball.Why do you want to use VorpX instead ?
I want to play all my games in VorpX (even the ones that won’t hook and will need to use the desktop viewer!).
I’ve been using VorpX for almost a decade now, and my dream since was “Having 4K-like resolution on an OLED HMD, so I can play all the games in VorpX!” … and its very sad to get finally the HMD that can do it… but now VorpX is the one that is bugging out (or limited in some internal way) :(I’m also a professionnal game developper (and I have advanced 3D modeling, animation and rendering skills too but it doesn’t really matter).
Awesome! A fellow gamedev and artist too to boot then!
I’m a professional indie and AAA game developer specialized in 3D Character creation! Moved to Japan and everything to make my gamedev dreams come true and everything hahaha
If this forum had DM’s I’d definitely send you a couple to chat about it lolThere is no way I can see blurry letters in VorpX.
I know right?
Even the G2 has more resolution than the image I sent! (you can even see the aliasing in the letters!)But as we said, you may be right on a PPD limit. I wouldn’t be able to tell with my current VR headset, which is already better than most.
Nah… far from the PPD limit still (sadly lol, its “only” around 45PPD).
Since you have a G2 it is easy to realize. For every 1 pixel the G2 has, the MeganeX8K has 3.
I’m not even getting to the 24PPD from the G2 in VorpX right now I’d bet :(I never use auto resolution, but most peope do, and as far as I know it limits resolution (it depends on game profiles).
Make sure you disable it if you want to play in very high resolution.
Of course, first thing I checked! I also disabled any sort of AA on both, to make the aliasing more obvious in both images and make comparisons better (very noticeable in the bridge ropes!).
Anyway, with hooked games, if you don’t see any difference between resolutions above 1440p or 2160p (or even 3200p), there is a problem somewhere, because it’s not the usual behavior.
I thought so too! That’s why I tried to reinstall a couple versions.
Reinstalled GPU drivers… and nothing.
The HMD is SteamVR native, so it should be acting just like the Index or any other native SteamVR HMD :/Everytime I tried, UEVR was particularly bad in 2D screen mode (a lot of aliasing and there is no curvature so there are distortions).
Dammit, weird again. That is exactly the opposite experience to what is happening to me.
In UEVR when I put it in 2D mode, not only the FPS boost up massively (due to all the processing that is not being done), but all aliasing instantly disappears (which… to be honest, makes sense, its stretching like a 4000×4000 image on a small square in front of me, instead of stretching it all over my FOV lol)——————————————————————————–
With the extreme resolutions you are mentioning, I think only the virtual monitor can reach, although it might currently be limited to 4860p max in the vorpX app.
That’s the thing. I made sure that in both instances, the game is running in 4860p. (I tried both by launching from the desktop, and the normal way without any differences)
The framerate matches 4860p on VorpX, the computer is using the GPU at an expected level… its just that VorpX isn’t showing the detail for some reason.
There may be be other special cases.
I tried many games, all of them max out at that very specific “VorpX” resolution. So does the desktop viewer (even when the desktop or the games are clearly set at 4860p!)
It’s important to note that you must have these custom resolutions created for a game to be able to recognize and display them. You test and create these in Nvidia Control Panel for your physical monitor, or the vorpX config app for the virtual monitor.
Forgive me if you already knew all this. I only mention this on the chance you are skipping something. like editing a game’s ini resolution without first creating the monitor custom res to match.
It’s the in game selected resolution that matters, not the SteamVR slider.
Nono, please, thank you for taking time to reply at all!
I did try all that. I made sure the games are ACTUALLY rendering at that resolution (checking not just the settings, but also GPU usage and FPS and such).
It really does just feel like there is an arbitrary “ceiling” I can’t pass when using exclusively VorpX :(
My SteamVR resolution is set at roughly 6100×5600, which basically 1.5x the resolution of the MeganeX8K (using up 100% of the panel’s image quality, which makes it equal in pixel density to a 4K 32″ monitor at regular viewing distance).And don’t use the Desktop Viewer (not to be confused with the Virtual Monitor) for games, always better to hook in with vorpX the intended way. Even for 2D play. The viewer is just capturing the desktop, performs worse, and looks pixilated.
Yeah, I tried both, just in case anything changed… and it didn’t :(
I don’t know if it helps but I tried to capture VorpX the last time I played Frontier of Pandora.
I’m sorry : it’s not the best game to show large outdoors environements because LOD and textures aren’t the best at long distance (compared to Metro Exodus for example), but I’m playing this game right now.It feels actually a lot more realistic in VorpX because I hide some textures defects with AMD Fidelity FX at max quality (without removing too much details on close environments).
It’s quite impressive even if it’s not as photorealistic and perfectly detailed as Metro Exodus. Anyway you don’t really know where to look because of the insane amount of objects so it works very well if you want to instantly forget about reality for a while !
Pandora Moutains in VorpX full VR Without upscale, enhancement filters and 3D :
It’s a lot better in VorpX. I think this is because you can’t see VorpX’s enhancement filters (upscale, sharpening, maybe supersampling, etc.), even without considering there is no 3D here.
If I look at these screenshots in a VR viewer, I have to imagine something twice as detailed, sharp&clear (and with 3D) to be close to the quality of VorpX (even in 2880p without FSR/DLSS).
Even if those are 3840p screenshot without noticeable aliasing.Lower FOV :
Vegetation – Close-up full VR :
Arches High FOV full VR :
The arche in the background is already quite clean on the screenshot. It’s better in the G2 with VorpX’s magic. It’s what I like the most in VorpX with a displayport headset. Things don’t get blurry even if they are very far from you. With Metro Exodus it’s a lot better. It depends on the the game engine.Trees medium distance Edgepeek :
Ikran (dragon) Edgepeek Full VR display mode :
A few limited volumetric clouds (not lucky with the weather yesterday).Clouds Godrays Edgepeek :
This one is not so beautiful but it’s funny with the godrays.
(This area is less beautiful except sometimes there is some amazing volumetric clouds / fog but I had no chance yesterday).
It’s interresting because you can see the outlines of the 3D objects.Sorry for the legend, this was supposed to be the first screenshot with relatively high FOV :
So I posted the same image twice…don’t look for a FOV difference haha (it’s interresting to see it in low FOV because high FOV is strange on a monitor, and if you play in immersive screen, you see a lower FOV because you don’t see the whole picture).
But in fact a properly configured game is always high FOV (usualy higher than that).You can’t use a higher FOV than 105 in this game so I guess it’s only perfect with a Low FOV VR headset (it’s Ok with mine). Most games don’t have this problem. I really don’t know why recent games sometimes limit FOV like that…
