I've noticed that after playing games for a while, my framerate will drop significantly. I've traced it to when my PCH temp hits 40 C. Looked at EasyTune6, and that was the default setting for a warning temperature. I increased that to 60 in EasyTune, but that didn't seem to change anything. It still stutters horribly as soon as it hits 40C.
Is there a setting or something I can change to bump that temperature higher? I think even 45C would do it. It feels like something is being throttled or deliberately slowed down once it hits 40C.
