I feel that I should be running my games with alot higher FPS than I am with the hardware I have. My system: ASUS P4C800 P4@2.5 ghz MSI Geforce 6600GT 1024MB Samsung PC3200 Microsoft Windows XP Home Edition (I installed it from a reinstall disk that came with a dell computer) I installed the 3Dmark2005 demo today and ran it, I never finished all the tests, but I was getting 1-2 fps almost the entire time for the two that I went through, and I never got above 30. Now those tests are pretty beatuiful looking and must put a huge demand on my hardware, but 1 FPS A SECOND?? I also run half-life2 at 30 FPS mostly, I set my resolution to 800x600 and all the graphics settings at their reccomended setting (AA, AF off) and need to be staring at a wall or inside a structure (where I am usually staring at a wall) to get a satisfactory framerate. I'm wondering if it could be my OS, I did use Windows 2000 for a short time and the two games I played then (Delta Force BHD and Warcraft III) seemed to run noticeably smoother than they did in my version of Windows XP home. So should I shell out the $150 for a copy of XP professional or would that not help very much? Some other things to note, my P4 has a FSB speed of 800mhz, however I can only get my RAM to run @ 333mhz (according to POST) I have looked through my BIOS and motherboard manuel over and over changing different settings but to no avail. I also have a messed up case with no panels, everything is opened, and I turn my computer on by contacting the two wires instead of pressing a button. I also don't have any fans for cooling the motherboard and everything on it, only the stock CPU fan, however I have never had any problems with cooling.
