MCC PC Stuttering

Everytime I try to play MCC on my PC, the game runs smoothly until I try to look, shoot, or move around at all. It stutters and freezes up so much that I can’t even play the game. I’ve tried changing settings around on my pc, switching to fullscreen in game, changing game settings, and uninstalling and reinstalling. None of these things have worked. The only thing that has worked is when I launch the game without anti-cheat, which makes it run flawlessly. After the great multiplayer showing of Infinite at this year’s E3, I’d love to play some Halo on my PC, but it’s unplayable due to this awful stuttering and freezing.

Have noticed some serious framerate drops, especially in Halo 4 PvP. Wondering if anyone else experiencing this.

I have the exact same problem, terrible drops in fps and the only thing that seems to solve it is launching the game with anti-cheat disabled.

I don’t know if you guys tried this yet, but I ended up completely deleting razer cortex and it fixed the problem for me. Hopefully that does it for you guys.
