Straight to the point. I recently removed my 9800 Pro from my rig for an ATI manufacture x850xtpe. Games didnt seem to be running quite as fast as I had hoped so I tried the CS:S Stress Test and ended up with results no higher than 89fps. No matter how high or low I made the settings, it wouldnt go over 89fps. I knew this wasnt right, I should be getting like 150 fps on my rig. I tried cl_showfps 1 and saw that my frame rate barely ever went over 60fps until the very end. It stayed locked in the 50s for the most part. I got a 3d Mark 03 score of 11700. Doom 3 runs on high without a hitch, Far Cry seems to be a lil sluggish, Halo never stutters, and Deus Ex 2 is fairly smooth. I have all the latest drivers, and theres no way its my system. My rig is pretty much top of the line. P4 3.2 ghz OC'd to 3.5ghz, 2x512 pc3200 ddr ram, x850xtpe, 1 WD 60 gig 7200rpm (windows drive), 1 WD 120 gig 7200 rpm drive (steam installed). Asus mobo 800mhz fsb, 420w Thermaltake PSU. I really hope someone knows whats wrong, because this is driving me nuts.
