Terrible stuttering/fps drops in AC: Brotherhood
I'm having an annoying problem while trying to play AC: Brotherhood on PC: the game keeps stuttering, and every time it does I see my fps counter drop a few frames. With no frame-rate cap, I can get around 120fps, with the fps dropping to something like 109 when it stutters. I've tried limiting the fps to 60, but then the stutter still happens and the fps drops down to 57 or even as low as 48fps.
I don't have v-sync enabled (using a g-sync monitor). I've tried launching the game through uplay instead of Steam. I've tried changing the cpu affinity in the task manager, which worked ONCE. When I went back to playing the next day, it was stuttering again. I kept trying to change the cpu affinity like I did the first time, but it doesn't help anymore.
Does anyone have a fix for this? I can play the Ezio collection on my Xbox, but I'd really rather play it on my PC at 4K 60fps.
