I use a GTX1080ti for my main monitors and an RTX3080 exclusively for my Valve Index. This configuration works well with everything I've tried, except SLR, which has SteamVR tell me to move my HMD to the same GPU as my primary monitor.
Both SteamVR's and SRR's desktop windows display correctly, yet the HMD shows "SLR: waiting" forever.
Please fix this.
If you need help doing so, I'm a dev with a lot of experience convincing computers to do interesting things they don't want to... plus I'm currently for hire.
Thank you!
