Quest 3 fps drops frequently from 30-40 to 5-7 for 5 to 60 seconds and then goes back high again

the effect is so strong as if there seems to run another instance of oculus running in the background. Alt-Tab ing doesn't resolve the problem.

Do you have any idea?. I play normal oculus with cable.

More information please, did you just get the Meta update? PC specs, how do you connect, i.e.: Virtual Desktop, Meta Link with cable or Wifi? Are you running any OpenXR tools.

Sure sounds like something else is running too, have you checked taskmanager?

Is this happening at random? Is there something that seem it may trigger this, peripherals plugged in waking or sleeping? Maybe disable "hot plug" in the controls if it's DCS re-recognizeing any inputs you have plugged in?

It happens randomly just in cockpit, also when I return from 3D flying I get 25 instead of 75 in the campaign/mission screen for some seconds, then it tuns to normal normally. I don't get this in MS-Flight Simulator. I run normal oculus with cable link, no open xr. The task manager doesn t show any hints (at least for me). I have it for a long time (also before 2.9) Alt-Tab out and Alt-Tab in again used to help but it seems to get worse in the latest patch and Alt-Tab doesn't help anymore.

1. Did this just start?

2. What are your current DCS settings? Screen grab and post.

3. What are your Meta Link settings?

4. Meta Link software version?

5. Do you use any OpenXR tools? The recent Meta update created issues with some.

6. Use the VR preset in DCS and try again, any changes?

7. Are you using MT or ST for DCS?

8. Use Process Lasso to see what's running and to dedicate some cores to DCS only.

I have this for long time. I only have normal Oculus link wirthout modifying, no bandwidth limiter. 

It doesn t appear in non VR mode and in VR in the graphically demanding missions. They start with around 25 and then it drops to 5.

Another mission with over 30 doesn t drop. 

I use both MT and ST.

Latest meta version.

A 3060ti is borderline for a Q3. Have you tried using quad views foveated rendering in fixed mode? This will give you a massive performance boost. If you keep the centre to about 0.5 x 0.5 then you will reduce GPU load by about 50-70%. It will be more CPU intensity but a 5600x should deal with that.

This?

Put all your settings to minimum.

Screen grab and post your settings, including Meta Link.

No one can guess your settings and we really can't help you if you don't follow through. I just happened to be bored and looking around but soon this post will be old and no one will continue to help.

3060Ti is kind of a low and your processor is also on the lower side equivalent to an Intel i5-12400. So, you're going to need to use lower settings.

I run a 3080Ti and an i9-10900k and my settings are on the lower side for many things, but a few are higher such as clouds on ultra. If I remember later, I'll post my settings then go below them, though I use Virtual Desktop.

yes, thank you, the DCS-VR-settings are making it dissapear. So the VRAM may be the problem. I will then increase the quality step by step and see, when it is reappearing.

Until the last patch I could make it dissappear with Alt-Tab and then back again. That doesn't work anymore.

Disable ASW (in oculus debug tools), its very buggy currently. you need to disable at every session, as it doesnt remember
