Hi, I have an Asus P4P800 mobo with a pentium 4 processor running at 3ghz. I'm using 2GB of RAM with a Gigabyte 256mb GeForce 6800 GT video card. I have run benchmark tests using PerformanceTest on graphics processing and had 700+ FPS on 2D graphics, 90+FPS on 3D Medium graphics, but was under 10FPS on 3D complex graphics. These tests were run at 800x600. The card itself I know is not faulty because I've tested it in another computer and it performed beautifully. On any graphic intensive game, basically any HL2 game or mod, battlefield 2, C&C Generals, elder scrolls: oblivion, the games run at a very low FPS. However the graphic abilities of the card can be enabled, (HDR, pixel shading, etc) but even without these graphics enabled the game will still run very sluggish. This problem even occurs sometimes on very non-graphic intensive games, such as flash games. I'm wondering if anyone knows what the issue is, i've checked all the settings in the bios at least 5 times and they're all correct and all other benchmark testing was great, the only bad result was the complex 3d graphics test. Normal CPU functions run very well, i can alt-tab in and out of programs very quickly and can ran many programs at once, but since this computer is designed for semi-gaming, this fault is very problematic.
