Hi , I might be having a serious problem in which none of my games that uses Direct3D would perform well on my computer. Before I explain my problem here are my computer's specs: AMD Althlon XP 2000+ Geforce3 Ti 500 512 DDR Ram Nforce Asus Ultra Mainboard Windows XP Pro I have all the latest drivers for every single components in my computer. I am up to date with Direct X 8.1 Here's my problem.. Any games using Direct3D at no matter what video settings will run at low frame rate. My frame rate when playing any Direct3D games will just be extremely unstable. I usually use 1024X786 resolution. I get an average of 20 - 40 frames per second or lower on ANY games using Direct3D. And I would usually get a lot of slow downs in the frame rate. I get slow downs when like I am looking at sceneries that has a lot of stuff. I especially get slow downs during a lot of action in the game such as shooting , explosion ect. My frame rate would usually drop to around 5 - 15 fps when there is a lot of shooting in ANY games using Direct3D. While games using Open GL like Quake3 would maintain a high frame rate of about 150 fps at highest settings, even when there's a lot of things and action going on in the game. I play games like Deus Ex, Giants : Citizens Kabuto, Operation Flashpoint, or Morrowind. Now my question is , is this normal? Is anyone else experiencing this "problem"? Are Direct3D games suppose to be THIS slow , that the games are almost unplayable? If so why is it that most games uses Direct3D? Please help me out here... Thank you.
