Wanted to up the grafic level on Warcraft so I purchased new vid card. Its amazing compared to what Im used to. The problem I have is for 5-8 minutes I get 58-62 fps then it drops to around 7-8 fps. If I drop my settings to low I can still only get about 20 fps. After a few minutes without me touching anything they jump back to the 58 fps range again for a few minutes. It did the exact thing when I tried Half Life as well, great picture for awhile then gets slow then speeds up?? Open to any ideas. Thank you.
