(RESOLVED) Penumbra Performance Problems?

[MercenaryForHire]

hmm, your fan should be revving up when the game starts to max power and rev down when out of game. What is it doing in particular? Also check your temperature settings. This symptom sounds like you have a dead fan somewhere causing cooling problems. That could be another reason for bad performance. Your card could be overheating due to a blown fan. Another problem could be a dead case fan that is allowing your CPU to overheat.

It just runs full bore 100% of the time. I can ramp it down via RivaTuner, but it doesn't automatically clock back down to 2D speeds.

I remember when I used to play WoW, I started having real poor performance after looking inside my tower, I noticed that my main fan connected to the powersupply had burnt out. I used to get 60-70fps and after, I was getting 1-5fps because my CPU was overheating.

Temps are fine, CPU never breaks 50C under load.
