solved Mirrors cause black screen and water does not render with memory at the limit

[RED]

In the video you can see that mirrors cause black screen and water does not render. Turning off mirrors removes black screen in front of cockpit mirrors. You can also see that the memory is  at the limit.

I noticed this first in a custom multiplayer campaign with mods but only ~2000 units, so i reproduced the problem with the attached mission without mods.

The attached log is produced while capturing video 1.

No problem in 2D.

Note that if I see it correct the swap file usage is basically null for DCS.

All AMD system. OpenXR used for VR. RAM 32GB, VRAM 16GB.

I tried removing all mods, DCS repair and deleting shaders including terrain shaders.

Same issue here. Happens only in the Tomcat for me but has happened in the Hornet before on a playground mission with much less than 2000 units loaded. I wonder if the last OB patch introduced a VRAM leak?

Its been happening to me all night in various planes, Mc2000, Hornet, AV8B, so I need to turn mirrors off ??

Are you using openXR as well?

Yes but it did it Steam also on a clean install.

Copy, I have yet to test that. But that would indicate it is actually a DCS bug and not something else.

Ok, tested steamVR and no problem.

Ran clean+repair again, deleted saved games and ran with openXR again. Same problem. I think openxr is the problem. Log attached for that run. Maybe ED knows what is going on but they officially don't support it afaik.

Update: This doesn't seem to be a VR bug or related to openXR. See:

@NineLine feel free to move this thread. Do you know if this issue is known or was solved in the past?

Can replicate

I also did a clean install, and it continued to happen. I can run water on low. Disabled open XR and the problem persists. 

My game didn't know the difference until I accidentally activated the Hornets mirrors. Prior to clicking on the mirrors by accident, my game ran perfectly. Something happened at that very moment to cause the issue.

Any posts on water not rendering on a clean install either? 

Any chance this could be a graphics driver issue?

Open XR is the cause tested and confirmed.

Btw this is not an Open composite problem. It's reported for 2d as well and different hardware/drivers:

I was able to replicate by using the toolkit. Without the toolkit but with openXR works fine for me.

Try with OpenXR but disabling the toolkit.

Confirmed to be a bug in an old version of open composite. Now fixed in newer versions.
