I tried a handful of additional profiles and the only one’s I’ve found so far that do z3d are too low strength – essentially flat, if you compare them to tridef. Must be something strange with the depth buffer, maybe it’s logarithmic or something – I dunno.
The unity engine profiles do z3d but the effect is so weak you can hardly tell the difference. Some Unreal engine profiles try to reconstruct the 3d but it gets split down the middle of screen. So it’s kinda try the other profiles one by one.
I had a lot of trouble getting it to hook early on but the only things I think I changed was fullscreen to borderless and turned off antialiasing, so maybe it needs to be in a windowed mode.
I took another look at this and what I said about the game being hook-proof apparently was a problem in my system at the time, since vorpx doesn’t have any issue hooking it. I tried a few dozen profiles and a lot of them hook but none reconstruct the 3d.
I tried Tridef again and it works with the generic profile. There’s probably a vorpx profile that’ll do z3d as well, I just didn’t find it.
It may work with vorpx but I seriously doubt it – anything that messes with headset synchronization is probably going to make vorpx nauseous. Also doesn’t work with Rift or WMR headsets so probably isn’t worth the effort to make it compatible.
Quake 2 RTX uses the vulkan api, which vorpx doesn’t currently support. As far as ray tracing in general, I don’t think there’s a GPU in existence that can do G3D and RTX at the same time at a reasonable frame rate and resolution.
Distant objects look flat of course but up close your ship, the other ships, asteroids, space debris, etc. look pretty good. Given the type of game, I’m not sure that G3D is going to buy you much except for a resizable HUD and a 50% performance penalty.
None of the dx12 profiles work. They either cause the game to crash on startup, or don’t render the video to the headset or monitor.
Unreal engine, dx12 by default but dx11 can be activated with a command line switch or maybe in the steam launcher (I have the GOG version). RDR2 profile works for dx12, I tried Conan Exiles with dx11 and got G3D, but there was a lot of shader flickering. Probably a different profile would work better, but I haven’t had a chance to look any further.
I think you need to set your preferred processor to the nvidia gpu if you haven’t already done that.
You could try setting vr prerendered frames in nvidia control panel to a value higher than the default (1). It may help with link latency, might make it worse – can’t test it myself.
That’s close to the performance I get with my RTX2060 on ultra settings. Given that a 3080 is supposed to have an effective speed around 2.2 that of a 2060, I’d expect better performance too.
I use a Rift-S, not Quest2 so maybe an issue with the Link or the GPU is not being utilized fully.
AFAIK, supersampling in an hmd is just setting the render target to a resolution higher than it’s 1.0 pixel ratio. If you want to invoke supersampling from vorpx, you have to set your in-game resolution high enough to exceed that.
Tweaks via SteamVR or Oculus Tray Tool or whatever may be reflected somehow in Crystal Image – you’d have to ask Ralf about that. Vorpx has the final say in the render target size, irregardless.
No problems hooking, but I’m seeing shaders flashing on and off on the map. Not sure if it’s the game or the profile.
The last time I checked, Vorpx ignored SteamVR supersampling. Have you checked your pixel density to verify your changes are working?
