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.

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.

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!)
