Don’t know what’s causing it, but I can’t find a solution.
For whatever reason, using a mouse in matchmaking causes massive frame drops.
I get a steady 60fps while using a controller, and using a mouse used to work fine.
I haven’t changed any settings, and am still using the same mouse, it just… stopped working one day.
Interestingly, it only happens in matchmaking. I can create a custom game, and it’ll work just fine.
Second I try and use it in matchmaking, frames drop from 60 down to 15-20.
I’ve tried what was suggested in this thread here: https://www.reddit.com/r/halo/comments/e6l7al/halo_mcc_potential_pc_mouse_lag_fix/
I’ve also played around with the v-sync, framerate cap, and tried changing it from fullscreen to borderless, all to no avail.
