Re: 100% Disk Usage on C Drive (not where the game is installed) causes freezes

SOLVED! For anyone who's having a similar issue: It turned out to be the Live Replay Feature on my Radeon GPU driver. I've set it to record for 600 seconds (10 min) and to cache into the C drive. So I'm guessing the GPU runs out of memory during the game and starts using the C drive to cache the recording. I know Nvidia cards have similar features, not sure if they could cause the same issue though.

Ways to fix it: 

Turn off Live Replay to confirm that it's the issue. Leave it off if you don't want it. 

Change the Cache drive to a drive that's not C and not the drive the game is installed on

Reduce the replay duration so it doesn't take up so much memory and don't cache as often or as long.
