After finally updating my video card drivers (NVIDIA, version 304.64), I went ahead and ran TF2 to try it out. As soon as I started a match, I noticed that 1.) Steam was using most of my processor, whereas TF2 was barely up there, and 2.) Although cl_showfps showed that I was getting around 150 fps, it felt more like I was getting around 15 fps along with random moments where the game just freezes up for a few seconds. I've even set everything to the lowest settings possible and disabled multicore rendering, and it still has the worst performance I've ever experienced (even under Wine, TF2 was never this bad). After playing for a little while, the game also crashed (dmp file here
I'm just wondering if anyone has experienced this as well, and if so, has there been a way to improve the overall performance.
