I recently bought a new computer with an Nvidia 8800GTX, and the first game I installed was F.E.A.R. I performed the Stress Test and my FPS was almost always over 100FPS. Now when I perform the Stress Test, my FPS is, at the most 50 FPS. When I was getting 100 FPS, I had all of the settings to maximum and I had 43 programs running in Windows Task Mananger. Now I have 33 programs running and I am getting half the performance. Also, at times the FPS gets very slow, down to sometimes 19 FPS and this never happend before. Does anyone know why this might be?
