Re: Microstuttering + choppy, skipping frametimes
Interesting note - after a bit more testing, I've discovered that the CPU affinity 'solution' (unchecking CPU 0 and only leaving CPU 1-3 checked) definitely gets rid of the stutters and frame drops (even on maxed Ultra setttings), but it WILL eventually (after about 10-15 minutes of playing) lead to the game's framerate completely tanking into the single-digit numbers at some point. What's peculiar is that at that moment, my wireless Xbox One controller will also lose connection and the game will ask me to reconnect it. I'm not sure whether the controller losing connection is a result of the game slowing to a 3 fps crawl, or the cause of it. Maybe the CPU 0 core handles something with regards to the controller and turning it off leads to the controller losing connection and tanking the game's framerate?
Changing power usage to Maximum performance in Nvidia CP didn't help (it was initially set to the default Maximum power, not Adaptive, for me).
Honestly, I don't know what to do now. Stuttering is really obvious and experience-ruining on certain tracks, and the CPU affinity trick works for about 15 minutes, but then seems to completely choke out the game, with me needing to restart the event or the whole game...
