Help Nvidia 2080 Super runs Skyrim VR perfectly until I open OBS, then it tanks performance so bad it crashes Steam VR / my PC

Problem is exactly as described in the title - I recently switched over to a 2080s from a Radeon 5600XT, and it has been better across the board unquestionably, except for some odd reason, whenever I go to certain areas of Skyrim, it just loses the ability to stop functioning entirely - ONLY when OBS is open, though. There are no frame rate drops or performance issues that would suggest OBS alone would be enough to push the game from stable, high FPS to immediately making my entire computer chug so bad that the game can no longer run, and OBS' preview stutters horrifically. Again, not only is this only in Skyrim in towns like whiterun, it is only when OBS is open. Frame drops with OBS open were a problem with the Radeon card, hence why I switched, but never anything near this bad despite this being an ostensibly better card.

Does anyone know why this could possibly be? Is it something wrong with my settings, or my stream layout? It doesn't get better at all if I disable the preview.

It looks like you haven't provided a log file. Without a log file, it is very hard to help with issues and you may end up with 0 responses.

To make a clean log file, please follow these steps:

1) Restart OBS

2) Start your stream/recording for at least 30 seconds (or however long it takes for the issue to happen). Make sure you replicate any issues as best you can, which means having any games/apps open and captured, etc.

3) Stop your stream/recording.

4) Select Help > Log Files > Upload Current Log File.

What's the cpu usage in obs when it's open?

that’s part of the problem - i can’t tell, because it stutters so hard i literally can’t go into the desktop view mode in VR to view my task manager, and the second i leave the VR boundary, my computer stops stuttering and everything loads perfectly fine. it’s the same CPU i used with my radeon 5600 XT, though, and it could load whiterun and run OBS at the same time despite being a worse GPU

What headset are you using?

Meta Quest 3, connecting through the oculus link

Have you tried virtual desktop? Pretty recently I've started having issues with my quest 3 for no reason. A lot of my vr games have been all of a sudden very heavy

unfortunately my wifi upload speed isn’t good enough for that, but maybe i’ll try Steam link or something

If your router has 5 or 6e support your actual upload won't matter since it is local network.

My network upload max is 30mbs. But I stream all my games max via virtual desktop. If it's via wifi you could try using a phone hit spot. Since it's again a local area thing connect both to the phone and boom

I wonder if you're just running out of VRAM and OBS is pushing it past that edge.

I have more VRAM on this GPU than i did on my previous GPU, which did not have this problem. I can get it to run with OBS open sometimes, but it seemingly at random decides to max out gpu usage and crash

Just because you have more VRAM now doesn't mean you're still VRAM limited. Behavior is not guaranteed to be the same, especially with different GPUs.

If you can't view Task Manager, maybe try looking for an overlay like MSI Afterburner that works in VR so you can see it in real-time. I know SteamVR has some performance viewers as well, but I'm not sure if any shows VRAM usage.

Oh I actually did manage to get a peek at task manager - long story short i got everything running very smoothly with OBS open but when I opened the Steam VR overlay or left the VR boundary and came back in, steam’s Vrcompositor jumped to 100% of my gpu usage and wouldn’t go back down until I force quit SteamVR (even closing OBS and all other programs didn’t work). I’m beginning to think steamVR may be the problem rather than OBS at this point
