I have been having lots of issues with VR in both v4 and v5 over the past couple of weeks. Sometimes VR quits with a GPU error message and bounces me back to 2D, sometimes it crashes the whole sim. Sometimes my POV floats around even though I have defined the VR area and re-calibrated the origin. No issues in any of my other VR games.

Steam VR released a major update on Jan. 4 which, according to the site, has enhancements particularly for AMD Radeon cards. That is what I use, and that is about when my problems started. Maybe these have bugs. Interested in hearing, especially from other AMD users, whether you are also having issues.
