Steam VR and Reverb G2

[Leodagan]

Greetings to all,

Looking for feedback about config in SteamVR. I have a Reverb G2 and running on a RTX3080Ti.

What should be the resolution in SteamVR? I read previously that it should be at 50%, which corresponds to the resolution of each eye. Is it the way to go? Should it be increased ? (without going to 100%). Is it better to increase to resolution there and not using supersampling in game? (in Elite for example)

What are your experience and settings?

Thanks!

That's nonsense. With a GPU that fast, you will probably want your resolution set at 100% or more.

To optimize resolution, Turn on your GPU frametime wrist display:
From the SteamVR floating status window, go to the settings menu> Developer dropdown menu> Advanced Frame Timings. That opens the fancy graphs on your desktop.

Below the graphs is a checkbox for Display In Headset. Check it. Your right wrist now shows the graph in VR.

At 90Hz, you need frametimes below 11ms. So lets say you get simple game and your wrist graphs says you are running 5ms frametimes, so you could double the resolution (to 10ms frametimes). Just press the system button to bring up SteamVR in game, press Video Settings, and there a slider for just that game. It multiplies with the global resolution slider. Turn it up to 200%. Now you are running that simple game at the highest resolution your card can handle and still make 90 Hz refresh. If nothing changed then you need to quit and restart the game for changes to take effect... depends on the game. This is just a mathematicaly simple example, I wouldn't go above 150%, because it's better to leave yourself headroom if the game has a complex scene, and resolution over 150% gives almost no visual benefit.

That fast GPU with that HMD should always make framerate at an acceptable resolution, but if it won't make 90 HZ at an acceptable resolution (like on a complex flight sim) then you'll have to keep frametimes under 22 ms (at higher resolution) and live with 45 real fps, re-projected to 90. Re-projection takes the last frame and moves it the opposite way your head moved in the last 11 ms to keep your visual field at 90 Hz and fight motion sickness when your rig didn't make a real frame in 11ms. Motion Smoothing is a fancy kind of re-projection that tries to also guess about how on-screen things were moving, it takes a little extra GPU power and only looks better in some cases.

Depends on the game. I usually stick with 150% but sometimes I'll go up to 300. I recently tried the Cyberpunk vorpx mod and the game looked terrible at 150% but it looked pretty good at 300%. I don't recommend that game or mod though too many crashes and they're both too janky.

100% resolution is correct for the G2.

@TO

I have the Reverb G2 too (RTX 3090) and i play my Games without Problems on 150% (3892x3792 per Eye).

Yeah. Most VR games are very simple graphically and you can definitely upscale if your pc is beefy enough. I have an Index along with a G2 and when I use my index I always play at 250% to try and squeeze as much detail out of those crappy screens. It still doesn’t look as good as the G2 natively though.

Agree, therefore he should start at 100% and work his way up piece by piece. How much you can ultimately use varies from game to game like you said. I found my sweet spot at 150% with my Rig and in some Games i can go higher, but then i do not really notice much difference. The eyes gets used to the resolution very quickly anyway, so higher resolutions are great, but you can not see much differences between them. That must already be a big step than (at least for my eyes ^^).

Thanks for all your inputs, appreciated!

what would you guys recommenced for the reverb g2 and a rtx 2070 super?
