Hey guys. So I'm having an issue where while playing GTA 5, after around an hour or so, my GPU usage drops from the normal 98ish% to typically around the 60s. This results in my 80-90 fps in the city to drop to the 50s-60s. Additionally, my average CPU usage also seems to drop over this hour period. I still haven't come to a reason why but I have discovered that bumping GPU intensive settings in the game, like AA, returns the 60ish% usage back to the 98 average. Under the 98% load, my GPU runs at about 75 c. My CPU runs in the late 60's - early 70's temperature wise. I played in 1920x1080 res. Maybe you guys can get shed some light on this issue. Thanks for the responses.
