Finally consistent framerates on Quest 2

[av8orDave]

Figured I'd post some progress for anyone else that it may benefit...

Going into the weekend, I was getting inconsistent FPS with fairly low settings (on super basic single player scenarios, I'd get inconsistent FPS ranging from 25 - 75... on Liberation missions, I could get around 25 - 45, with fairly large swings). My system is Ryzen 5950X, RTX 3080, 64GB DDR4, SSD, Quest 2. I was running Med textures, low terrain textures, 2xMSAA, no shadows, standard clouds, 8xAnisotropic, no global cockpit lighting. I ran the Quest 2 at max resolution in the Oculus app, 72hz, no ASW.

On a whim, I switched from 72hz to 90hz, used Nvidia control panel to cap the framerate to 45fps, and switched low latency mode to "Ultra". I was shocked to see a consistent, rock-steady 45fps even in complex Liberation missions. I dialed MSAA to 4x, went from no shadows to low shadows, went to 16xAnisotropic, and even dialed the PD in DCS up to 1.2, and I'm still running a solid and consistent 45fps, only with significantly improved graphics quality.

I'd still love for the core game to be optimized for VR performance, but this is a huge improvement, for what it is worth.

Im getting 72 fps most of the time (even on some Syria airfields with the Viper) with the next options:

- Refresh 72hz

- Oculus resolution 4100 (dont remember exactly)

- DCS PD at 1.7

- Textures: Medium

- Ground textures: Low

- Water: Medium

- Shadows: High

- Clounds: High

- Traffic: Low

- MSAA: Off

- SSAA: Off

- Cockpit Global Illumination: Off

- Anisotropic Filtering: x16

- Ground Shadows: Flat

The only mod i use is Fholger VRPerfKit, with FSR at 75% and adjusted FFR. GPU is undervolted, Quest options via Oculus Debug Tool:

- FOV: 0.92, 0.94

- Encode bitrate: 400

- Encode Resolution: 3963

- Link Sharpening: On

Flying jets has no problem getting 72 fps almost all time, on Apache depends on the zone, for example, Viper instant mission Free flight on Syria, where you spawn almost above city at low altitud i get 72 fps. You can see my specs on my signature, take a look and try

Am I missing something on signatures? I can't see your specs (nor anyone else's) when they say their specs are in their signatures.

Awesome, just enabled them. Thanks.

Is this still holding true? Why cap it in Nvidia CP, doesnt Low latency ultra do this for you already? What does it do when uncapped?

3060ti here and can confirm I see some great improvements. Used to also run 72hz no ASW but after switching headset to 90hz, locking Framerate to 45 in NVCP and low latency mode to Ultra I get rock solid 45FPS, even in the Marianna's doing traps on the SC with 4 friends...oh and I was the one hosting the server!

Only mod I run is Vrperfkit with FFR enabled and upscaling disabled.

[Outlaw]

Specs: 3080ti, 64Gb @ 3600Ghz ram and 9700k @ 4.7Ghz cpu.

Results: It actually lowered my frames. Used to have 45fps with occasional dips in all multi-player servers (dips happens when F14 spawn on ground or Awacs contrails).

With it enabled I get 35 to 38fps in multilayer servers.

Settings

NVidia Control Panel Shader set to 10gb (very important), VR Prerender FPS 2, Power set to Max

Resizable Bars enabled with VR direct X profile enabled. 

Mods Simple vr shader and Vrperfkit (0.9 using Cas)

Ultra Clouds & Visibility are probably the performance killers, on ultra clouds in a high density clouds evironment can take 3ms more than high clouds but own low density scenarios the performance could look the same as High, same applies to Visibility

What you mean with "VR Direct X Profile Enabled"?

I mean this (added all settings in signature)

Better 3d VR

Forgot to mention that I am using Open XR and deblotted nvidia driver How to De-bloat Driver

What is your Oculus resolution set at? I seem to get the best performance with Oculus render res maxed out and refresh set to 72hz, ASW off. I'm using VRPerfKit and Kegetys shaders.

i7 10700k, 3090, 64GB

All the way to the right, DCS PD set to 1.0 and in the oculus Debug tool I have Bitrate at 550, encode resolution width to 3664, link sharpening on and both ASW and mobile asw disabled.

 

Beyond that, I also use side quest to set the Quest's default texture resolution to either 2094 or 2512(might be slightly off on the values, doing this from memory). I've heard this doesn't effect link/pcvr but I definitely notice a clarity difference.

Hmmm, might have to try Side Quest. Never heard of it.

Is the resolution feature on SideQuest working again? I used it way back when, but it stopped working following an update and the community had no estimate on when / if it would be working again.

Nice, I’ll have a look, and thanks for the heads-up.

Something I dont understand about Steam VR with Oculus 2:  to use the cable link option (for best FPS) do I not need to run the Oculus PC app first?  And, if so, what is the point of running Steam VR overtop of that?

[Laidback]

I'm not using Steam VR with Oculus.  Only the Oculus tray tool with link cable.  I'm getting smooth 45 fps with an i7 and 3060ti

There is absolutely no need to use SteamVR with Oculus (link cable or airlink). Oculus has its own runtime and works fine

Works much better than running it through SteamVR

But how do I do that when I need the Quest hard wired link?

Quest2 uses its own built in software.

Run it .

Set to 72hz max slider 1.7 

Run debug tool . Copy what's said here . 

Download sidequest run and copy resolution as above. For clarity. 

No need for steamvr .

Thank you for the tip, I'm trying your settings right now (my specs : 3060TI, Ryzen5 3600, 32GB)

It really seems to smooth things out, Mariana is still stuttering at low altitudes. Now I have yet to see if the unexpectied stuttering on carrier is still here,

[Steel Jaw]

So this is not using the OTT?
