FPS degrading while being in a match
My friend has a problem where after joining a game either practice tool or a normal ranked game the fps starts with 100 to 150 and when exactly 10 minutes pass it drops to 30-40 fps. Either fast forward in practice tool or normal ranked game time. It needs to be mentioned that every other game works fine without any problem except league.
Specs are :
CPU : Ryzen 5 3600
GPU : RX 6650 XT
RAM : 16GB
In the video you can see the start of a test game in practice tools but i cant attach the pic showing 30 fps after exactly 10 min have passed, so im thinking that rules out any cpu overheating problems since the test has been concluded by fast forwarding 10 minutes in practice tool and not actually having the game run for 10 minutes please correct me of im wrong.
