Stuttering during Halo 3 campaign (PC)

Just 2 minutes in and I’m experiencing frequent game hitches on Arrival and Sierra 117. Going to try and restart my PC to see if it fixes the issue. The stutters are happening in cutscenes and gameplay.

It happens in multiplayer too. MCC is basically unplayable for me.

(Switching to Fullscreen fixed)

I did restart my computer and it seems to have fixed the issue for now. Haven’t gotten around to multiplayer yet, but have played up to Tsavo Highway with no issue since the restart.

If full screen fixed it, do you have more than one monitor hooked up?

same as above,

stuttering on any resolution. unplayable. 3900x and 2600RTX Super…

This is STILL an issue for me. 3060Ti … Really frustrating.
