My Ti4600 died and I replaced it with a new 9800pro 128MB card. Everything seems perfectly functional except I get really poor performance in 3D. Counterstrike, which maintained 100fps most of the time with 4XAA and 8X ansio with the 4600, drops to 20fps sometimes with the 9800pro with no AA and no ansio and performance-oriented settings. Something is definately wrong but I don't know what. I have an Athlon XP2200+ on nForce1 based Asus board, 2x256MB PC2100, and a brand spanking new TruePower550. My WindowsXPPro was just freshly re-installed and has been fully updated. It seems very odd that my ti4600 outperforms this 9800pro. Any suggestions?
