About a month ago I wiped my computer and re-installed everything, including my entire Steam account. About 2 weeks ago I got a new monitor, 1920x1200 up from 1280x1024. I sat down today to play through Portal, again, but I get frame rates of 2-4 fps. Even with all graphics settings on low, low res and even in a window. I tried HL2: EP2 and TF2 but get the same result. All over steam games work perfectly, as does Supreme Commander and UT3. By this I mean frame rates in excess of 100. Specs: Core 2 Duo E6600 2.4Ghz 2GB RAM 8800GTX 768MB Creative X-Fi Xtreme Gamer I have done all I can think of, any suggestions?
