I asked about this in the OpenComposite Discord (there's a link on the Gitlab page: https://gitlab.com/znixian/OpenOVR), and I was advised to turn Motion Reprojection off as a workaround.
I had been getting the `xrWaitSwapchainImage timeout` error after opening the F10 Map in DCS (but also saw it sometimes on mission load), and only while running OpenComposite (not SteamVR). I got the error on both the Stable and Open Beta versions of DCS (2.7 & 2.8). I'm using the per game installation of OpenComposite (`v1.0.933` at the time of writing), not the system wide installation.
After turning Motion Reprojection OFF, I haven't seen the error.
I do think that things were slightly smoother with Motion Reprojection on, but it doesn't look like that's an option for now. I was also told in the Discord that there would be a fix for the issue in an upcoming version of OpenComposite, but there's no ETA as of now.
If anyone in this thread has OpenComposite working with DCS with Motion Reprojection ON, I'd still appreciate any advice! Hope this helps.
