But in xp brotherhood, cod waw fps so low 5-19 with low resolution. I tried install 7600gt driver, it work great. And fps raised 20-40fps. I think my card not real 9800gt. Any solution? And before install driver i edit nvae.inf and write "%NVIDIA_DEV_039f = nvidia 9800gt " without this line nvidia installer says" cannot find compatible graphic hardware" help mee. My system: intel core 2 duo e4500 2.2ghz, 4gb ddr3 ram 2x2gb, q45 mobo, 450w psu.
