So, it didn’t solve the problem completely (still experiencing the map stutter issue though I swear it’s not as long of a stall now) but the solution mentioned in this post of disabling the new Target FPS setting seems to have improved overall performance a LOT: FPS dropped from 100 to 40 since yesterday - #42 by Gradius-malganis
Edit: Ok this definitely hasn’t fixed the map stutter and quest objective update stutter, but between those events I’m getting better FPS with the Target FPS settings turned off, so they may be unrelated issues that were both causing poor FPS.
