I'm getting these purple lines in the SteamVR frame timing graph that correspond to little stutters that are most obvious when turning my head. My frame timing is fairly good, from 10.5ms to 12ms looking at cities, but these spikes are always there.
First shot is flying, looking at reasonably uncluttered area
What's weird is, they're always there, even in the menu, but they go away if I alt-tab out of DCS.
Second shot is in the main menu, 4.5ms frame times
I've unplugged everything USB, I've killed background tasks with wild abandon, I've updated gpu drivers... about the only thing I can think to do is flatten windows and start over, and I'm trying to put that option off as long as possible. Any suggestions?
