Very low VR performance

[Keton22]

Spec: Quest 3 over Virtual Desktop (tried both SteamVR and VDXR), 4090, 7900x, 64GB RAM, game runs from 8GB/s NVME

Game set to 'medium' with DLSS Balanced goes all the way down to 30FPS inside of golden dome, near the linking book. In plenty other regions runs around 45-60fps which is not enough for VR. If tyou fiddle with the settings sometimes it runs fine for a moment and then drops back to low FPS.

In flat 4k it runs at locked 120fps maxed out.

Something wrong on your side. I'm playing with most stuff on epic and some on high, no DLSS at like 3500p and I get 80fps with the 4090 and 13700k.

I'm having the same issue. In open spaces it runs really bad, unplayable. All my CPU/RAM/GPU usage is low to medium. I even set graphics to low and had the same issue. It even runs VERY slow when just having the menu up. I've updated to the newest beta of Steam VR, updated my Drivers, feel a little stuck.

I'm having it pretty bad too using Steam Link (Air Link for some reason is bugged on my Quest 3 and I can't connect it period for any game).

I'll either have to do tech gobbledygook to get Air Link working again, try Virtual Desktop, or maybe just shell the money out for a native Quest version (but then lose the progress I made on the SteamVR version)

I think I might have the same issue on a different headset? I'm running on an Index. Performance in the golden dome is buttery smooth on flat and unplayably jittery in VR. I do have one of the "weird" CPUs (13900KF) but haven't gotten any errors on startup.

I'm curious if my performance issues are just related to my old rig, or if there might be something else at play. I've been pleasantly surprised that my comparatively-ancient graphics card has punched above its weight on many other games (like the now 4-year-old Half-Life Alyx), but this one seems to be too much for it to handle.
With the Autodetect quality settings (which seem mostly medium) I'm getting a lot of smearing (reprojection?) when moving or just waving my hands around. For instance, vertical features get "wiggly" or "wavy" when they're moving. It's pretty wild when looking through grated windows especially.
If I crank my quality down to low, the smearing settles (suggesting that yes, it's a performance issue), but something else seems off - possibly the "detail distance" or something like that.
And while I know VR is considerably more taxing than pancake, flatscreen performance is perfect with most everything set to Epic (as selected by Auto-detect).

I'm on a lower end system but the game is entirely unplayable for me even on the lowest settings (which look abysmal). Some times I will get smooth performance but once it tanks, it doesn't come back. I'm not sure what can be done.

I have the same issue Quest3 across cable link, i9-12900H, 3070Ti. I can't get past the first cutscene once linking to Riven - I get the hourglass and then it crashes. I mostly went for this version over native quest so I would have the option to play pancake as well. It might just be my specs can't run it well.

[Keton22]

something weird is going on. I've set the game to windowed and medium in flat screen and now setting it to high in VR produces playable results. Also injecting UEVR into flat screen game gives much better performance than native VR mode.

Interesting! Are you saying that you launched the game in flat screen, changed the settings to medium, and then picked up your headset? Or did you first close the flat screen game, and then relaunch in your headset?

Usually if performance tanks and doesn't come back it means VRAM filled up and isn't emptying right. I've seen it in many games like DOOM Eternal, Cyberpunk, and Dead Space. The fix for that is restart the game and lower textures and base game resolution either(which for this would be setting resolution upscaling to Performance or Ultra Performance or directly on the headset itself).

If it helps anyone to try it, I used the fix in this thread: https://steamcommunity.com/app/1712350/discussions/0/4407416886082950276/
and it solved my problem. The graphics aren't perfect by any means, but at least the game is playable for me now.

Ihad probelms with my airlink also untill ifigured out going to device manager and "disabling" then reanbling it fixed the problem for me..give that a shot

I'm just about at barely playable frame rate on my 1080 ti, no way on a 1080. Games use different game engines and optimization techniques, bring up Half Life Alyx is kind of pointless, source 2 is heavily optimized for VR.

You're fantastic, and thank you for offering a solution! The problem is I'm an IDIOT and had not updated my drivers. My performance is absolutely fine now!

As an update for me (on a Valve Index with a GTX 1080) I found that turning off "Motion Smoothing" in SteamVR settings made a world of difference.
I'm pretty tolerant of a slightly-too-low framerate, but the Motion Smoothing artifacts made it so I had to turn the quality\resolution scaling down farther than was really necessary, and in particular made the books especially hard to read.
