On Crystal Super, any and all settings games and desktop view is low res without clarity maxed it’s completely illegible to make out anything. Somethings bugged and I’ve seen enough similar posts to do with resolution bug or artifacts aliasing just people phrasing the same issue differently and not really getting answers. Just want to confirm these people aren’t making it up.
I can side by side with the stock pymax desktop viewer, steam vr desktop viewer or any other app, something about vorpX is coming out at 20% resolution if that of whatever resolution it’s told to be in games or desktop mode. I don’t pretend to know why but its a reality let me know if you learn a fix for it, unusable as is.
Please make sure to reset any SteamVR settings to default, same with the Pimax software. In the last “low resolution” post here in the end it turned out that the OP wasn’t able to go beyond 3000p. Even if you want to call that an issue, it’s probably a lot more than you are running your desktop with. So there has to be something else going on with your setup. vorpX captures the desktop at the res it is running at, same for games.
Aside from resetting everything to default: In case Pimax in the meantime has developed an OpenXR driver that doesn’t just use SteamVR’s OpenXR wrapper, switching to OpenXR instead of SteamVR in the vorpX config app might also be worth a shot.
Doing more testing today I can actually see it happen live, I’m in VorpX in a game, I change the resolution, when it applies its crystal clear looking like what it should be for about 2-3 seconds, it then disappears in the headset and reappears about 50% the res of what it was (Not in setting just in appearence). If you can guide me to what’s breaking or a work around would be huge and likely for a lot of people experiencing this. I’ve tried all the Device Selection Configs it’s all the same result the issue is 100% some interference between pymax and vorpX or something but how I described it is whats happening, I could try film it in through the lens to show you but take my word for it.
Even the Vorp HUD I bring up is pixelated low res, I do look forward to a fix. Could make for some legendary experiences otherwise
Sounds as if the game switches back to a lower res, which would be super weird. Never heard of anything like that before. Try to add a custom res in the nVidia control panel and then switch your desktop res to that res before launching the game. Some games limit their resolution to the current desktop res. A step-by-step guide for adding custom resolutins can be found in the vorpX help.
Running a game windowed may also help (again provided it doesn’t limit its window size to the desktop res).
If you want to use the full potential of your new Pimax headset you must run games at resolutions at or above 4K, i.e. 2160p or more. Roughly 3000p is what your Pimax Super wants as an input res with default SteamVR settings. Might be too much performance wise in modern games though.
If things still look pixelated when running a game at such high resolutions, there has to be something weird going on after vorpX sends the image to SteamVR, e.g. in the Pimax app or on the headset itself.
I’ll let you know if I ever get it working or pymax works it out, i’d be happy with 1440p but im getting like idk, 200p lol. Regardless of what resolution things say 4k by 4k looks like 200p in vorpx for me, Its a headache to look at so doing it every so often. Il probably just wait till pymax or whoever works it out. It’s a great idea.
Parenthesis : Even without any bug, I don’t think it’s possible to use full potential of a 8k VR headset (especially with SteamVR). It’s probably not useful to most people anyway.
There are a lot of recent games which are a lot more detailed and beautiful in 3840p (5120×3840) than 3200p with VorpX on my G2, even if it’s a 2160p VR headset. It’s probably because the details you can display with a 2160p VR headset in certain games aren’t computed without supersampling (at 3840p, I never tried more).
I may be wrong, but this kind of 8k VR headset are great to get “perfect” PPD if you have a perfect sight, but only with very old (or not demanding at all) games.
In my opinion, most old games, even beautiful ones, are already great in 2880p (in my G2) because there is a limit due to the textures of the games. You can already perfectly see the defaults of the game itself, even if VorpX enhances graphics a lot. I only used 3200 and 3840p with very detailed games like Metro Exodus, Atomic Heart, etc.
Considering 8k VR headset may be more demanding than a Reverb G2 (WMR/OpenXR/2160p), it could require a better graphic card than my RTX4090 to achieve the same result in some cases.
I think a 2880p VR headset like Pimax Crystal Light has already too much resolution in most cases. Some youtubers with RTX4090 seems to prefer G2 over Crystal Light on a same game, even to use UEVR, for example. There must be a reason.
Note : a VR headset with higher FOV may require more resolution to achieve the same result so it has to be taken in consideration here.
Maybe you have the Pimax DFR on. I switch that completely off when playing with Vorpx coz I’ve noticed that it does not work correctly and can cause pixelation right in the middle of my view.
@Benedict81 Nah, it happens in other HMDs as well like the MeganeX8K. I think its a bug on VorpX side that Ralf seems to have issues checking out (since on his side it looks like its working as it should).
@Boblekobold
Like I told you in other cases… 2880p is not even close to enough resolution, 5500p is still not enough resolution (although it really is getting to heavy diminishing returns there). So people with good eyesight can see a very obvious very clear difference (after all, its almost twice the amount of pixels)@Benedict81
Oops, disregard my last message. Seems like 25.1.1 fixed that issue by 90%.
It looks now great, even when running lower resolutions like 2160p, the image is rendering properly and its perfect!
