Have you tried tips from the FAQ thread?

Yes, anything I can find that might be related. I've run the game in windowed mode, disabled all other addons, and I'm doing it in a simple map. I'm also using a quest 2 and VD if that matters, though every other VR game runs fine so it probably isn't that.

I use Quest 2 with VD on an Intel HD Graphics 4400 and it displays on my HMD just fine. Probably has something to do with how your graphics card renders DirectX or OpenGL to other devices.

I've heard other people having the issue have AMD cards, so it's probably something to do with that. Just hoping there's some solution because i'd love to try this.

Something about recent vrmod updates has broken AMD GPU support+WMR it seems, it was fine until it's most recent updates

UPDATE: I've fixed it! (For now), not sure if you are on WMR or not, but this worked for me:

It's caused by some changes in the upcoming build to WMR's steam support, for some reason it breaks Gmod's rendering, I'm not sure if this is on Catse to fix or if they're even able to fix it, it may be an issue on Microsoft.

To fix it, roll back WMR's beta back to their last stable release, then VRMod should work fine again. It is NOT an issue with AMD GPUs as I and some others thought it was, at least not for WMR.

Unfortunately I'm using a Quest 2 with VD, but I'm glad you fixed your issue!
EDIT: Just wanted to add, it's odd that an AMD GPU works fine with WMR but not on Quest 2. Would lead me to believe it's a problem with Oculus somehow, and actually looking back at any other threads with the issue I can see, it seems like they all had Oculus devices too (not specifically the quest).

Thanks! And sorry to hear you aren't able to use this fix as you're on oculus :(

I do think it's strange that both oculus and wmr headsets have broken on AMD GPUs lately (though just beta for WMR).

Are you in any kind of beta for your headset's software? maybe try opting out if you are

I hope you are able to find a fix of your own soon for Oculus headsets!

Update: I found a solution to this! After contacting Oculus support because my Air Link wasn't working, they had me uninstall MSI Afterburner as it "caused their systems to crash." From there it's worked fine using Air Link. I haven't been able to test it using VD now to see if it was that or using Air Link that fixed it, but I'll edit this as soon as I can.

I use air link quest 2 and when i turn on gmod vr it shows on my monitor but the headset is stuck saying next up

Randomly works for me. Disabled everything except VRMod, worked. Re-enabling any other addon permanently broke it again!

Edit: playing around with "theatre screen mode" apparently fixes it.
