Halo reach PC choppy fps PLS HELP

ever since I downloaded halo reach on the pc the game randomly becomes so choppy that it looks like it goes down to like 10fps, it happens multiple times every game. My game will be running just fine and then randomly get choppy and jittery when I move my mouse around, it causes me to lose fights and sometimes the whole game its super frustrating, the only way to get it to go back to normal is for me to ALT-TAB out of the game and then ALT-TAB back in, it seems to run perfectly fine after that but then it will happen again a few minutes later and I have to do this multiple times every game I play…

ive tried uninstalling and reinstalling, verifying the game files and updated all drivers, nothing seems to fix it.

I don’t have logitec so its not a logitec issue

and yes my pc is more than powerful enough to run this game… does anyone know whats causing this and/or have a fix?

im desperate to try anything ive been waiting all year to play this game on pc and its just not enjoyable right now.

Are you playing in windowed or borderless fullscreen mode? For whatever reason my game randomly locks itself to 20 fps like how you described when running in a window, switching it to fullscreen fixed the issue for me.

yes I am playing in fullsreen… ive tried every setting… ive tried uncapped frames, with no v-sync then with vsync and capped at 60 with vsync as well as no vsync, ive tried different resolutions… nothing works, its really frustrating it happens like 6-7 times a game and a lot of times is the reason I lose games… im at the point where I just kinda stopped playing, which is a shame cause I want to play.

also here are my specs so you can see its not an issue with my pc:

BUMP - I’m having the same issues. Random choppiness. My computer specs are near top of the line with 144hz monitors. I consistently run 200+ fps and yet the game goes choppy as seemingly random times. Really frustrating.
