VR performance issue

Hi,

i would really need help to figure out the reason of my stuttering issues in odyssey. Stutter occurs being in front of a station (or inside of it) and in combat zones (with ~40 FPS).
All frames are beyond the line in the steamVR performance graph, but with orange lines ('reprojected w/o motion smooting') mixed in, when stuttering occurs (even if motion smoothing is turned on).

settings: vr low, SS 1.0, HMD 0.85, WMR: 60Hz, AA: off

windows taskmanager: GPU at 40%, RAM at 20%, CPU at 18%, SSD at 0%

Meanwhile i tried every combination of SteamVR, WMR and Elite settings without any success.

lowering the settings doesn't seem to have an impact at all (even with setting everything to low, supersampling 0.5, HMD 0.5, and resolution 20% in steamVR).
The HMD is connected via USB 3.0 superspeed and displayport. I have formated my PC, installed current drivers for GPU, CPU, motherboard; installed Win11 updates, I also uninstalled the xbox gamebar, just to be on the safe side.


Win11
HP Reverb G1
Readon RX 6900xt
AMD Ryzen 9 3900x
2x32GB DDR 3200MHz RAM
Rog Strix B350-F

There musst be something going on with my setup, otherwise performance should get better with setting everything to the lowest possible.

Any clues/recommendations?

Would suggest you look at what background processes are running. I have de-bloated W11 considerable (both manually and with some tools like "Winaero Tweaker") and have improved overall PC performance, but not managed to totally eliminate stuttering, althought it's not that bad. W11 also has telemetary activated by default (Microsoft love to know all about you) and can be disabled via Reg Editor, see below.

Regarding telemetry: i created the file 'AllowTelemetry' as shown by you (as it was not there for me)

Things to check: HAGS on/off, force DX11 mode in WMR for SteamVR.

i forced to DX11, no visible improvement so far; HAGS is not supported for the 6900 series

But already thanks a lot mates, these are exactly those 'special' settings i am looking for (y)

Alright, it seems that my issue is solved now:

  • updated bios
  • set performance in bios to ASUS enhanced profile
  • enabled DOCP in bios to let my RAM work with 3200 mhz instead of ~2200

Now i can finally turn loopings in stations without missing out a single frame (motionsmoothing off, SS 1.0, HMD 1.0, WMR: 60Hz, AA: FXAA)

There are so many things to check these days for VR. They need to offer university courses on how to get EDO and VR to run ok.

A few key things that can help

  • Dont forget to install the AMD chipset drivers as well as GPU - available from AMD site for your particular board ie x570 etc..
  • Leave SteamVR on 100% resolution and try all your res tweaking in EDO itself. Since your AMD probably use FSR option and start at Quality and work your way up or down
  • some settings to try in the AMD GPU settings

- Add your exes to windows graphics settings as per below to high performance

Thanks mate, i updated chipset drivers, set ED:O to High Perfomance in Windows Graphics settings and set texture filtering qualitys to 'performance' in the AMD tool. For tessellation i kept it on 'AMD optimized' but I will keep it in mind (as after minor research i am not sure if ED uses it).

Old VR necro but I've been playing now for over a fortnight without issues so l thought I'd share some info.
9900k on a z390, 3090fe, 32g ddr4 4kmhz, G2 reverb v1 (no cable issues).
Mostly on ultra, even ultra+ ingame
SS 1.0, hmd 1.0, bloom n blur off, fx quality & ambient occlusion medium.
Steam slider on 100%, per application slider (in steam vr video) 150%.
On foot a solid 90fps never flickers. But that's using the ingame Periscope view.
In cockpit its about 65 to 85 fps with 11 to 14% reprojection which is hardly noticeable.
Buggy is the same as ship but alot more reprojection at 20%.
In BIOS I overclocked the cpu boosted the cores so they all are used, and created a fan curve for the expected heat.
Cpu according to vrfps is at about 11% all cores or threads wotever all working.
Vrfps also shows the gpu at about 90% +-5%.
Almost all green but when it does spike there's no pink anymore just orange.
Chugs along nicely and I'm really fussy about rendering.
I'm out in the black so can't tell what it's like at an orbital but it's lovely out here.
Just checked its 3900x per eye. Sheesh.
Also there's an option in win 11 to enable gpu scheduling. Switch it off !! Gpu drops to 70% usage peaking at 75% and framerate drops too. Duno if Windows intended thus to allow for extra load ie a orbital approach or combat etc...but for me it's off...sod that
