Excessive view latency with Bigscreen Beyond #864
Description
When using SteamVR on linux with the Bigscreen Beyond 2e, the viewpoint lags behind the head position. I don't know the technical reasons but it makes for a very nauseating experience. When using the open-source Monado the equivalent issue can be resolved using that software's XRT_COMPOSITOR_USE_PRESENT_WAIT=1 and U_PACING_COMP_TIME_FRACTION_PERCENT=90 options -- this seems to suggest there is a timing issue, possibly due to a lack of reprojection or similar.
Monado has other issues, and I'd very much like to have a working SteamVR experience with the BSB. It's very close to working otherwise. Filing this issue in the hopes something can be improved here.
