    Sometimes (maybe a little less than half the time) when I use Trinus PSVR, quit the program, and then use it again, the following bug occurs. When I move my head, it looks like two subsequent frames are overlaid over each other. You don’t see it when you don’t move your head because the frames are very similar, but when you do move your head the frames are offset, and e.g. if you have text like A / B it starts looking like AA // BB. Of course the faster you move your head the more offset the frames are, but it’s always noticeable and a pretty serious issue that makes it impossible to use. Rebooting usually fixes the issue.

    This was in 1.0 by the way, I haven’t tried 1.0.6 yet.

    issue still exists in 1.0.6. This is actually pretty common now. I’m not sure if this was so common in 0.9.9.

    the new version has a display refresh rate option, it is possible it changed to a rate that is not suitable for your hardware. Try changing between the different values (60, 90 or 120hz)

    it’s 120 Hz. It was always 120Hz and it always worked. The PSVR is 120 Hz, and my gpu (1080ti) supports that. Now, it also works at 120Hz most of the time, but not always, and then I have to reboot the pc. The issue started with 1.0, which didn’t have the refresh rate option.

    it could be related to some of the settings that were readjusted after 1.0: the drift correction or (more likely) the smoothing.
    if you run the empty SteamVR room, with the timing statistics enabled (in SteamVR settings), how long does it take to render a frame? 1.6ms, 2.7ms or something like that?

    It takes very little time to render a frame. I attached a screenshot of the debug view.

    I tried taking some screenshots of the bug. And captured a video. But they don’t show the bug.

    I took a screenshot using windows snipping tool, and the lines in the empty steam vr room look ok. But when I move my head left to right, the vertical lines are doubled up. I also captured video using OBS but that didn’t show anything. Still, I can easily see the bug in my PSVR v2.

    video capture:

    I took a video using my mobile phone to show the bug. The video is fuzzy and dim but you can see the bug in still frames and you can see it a little in the video.

    Note that in the screenshots a single vertical line shows up 3-4 times. If I look at it with my own eyes, I only see the lines twice. I think the camera shows the line 3-4 times because it records at lower Hz, so every frame the camera takes is several frames that the PSVR displays, so you get more copies of the line.
