Hello, BJC112. I currently run an Athlon Thunderbird 1Ghz, Asus A7V, 512MB Crucial CAS2 PC133 SDRAM, Win98SE/Win2k Pro, Asus V7700 Deluxe. I get well over 100fps, but at times, it does go down, mainly due to so many people on multiplayer games (25-30). I run 1024x768, all settings maxed. That provides a lot of action and processing power for your computer. I did have to type in under the game....press the tilde key, the key right to the left of the "1" to get the console...then type in (sans quotes) "com_maxfps 300". That will change the maximum fps to whatever you specify. I usually use something durastic like 300 to ensure the higheset numbers. I am not 100% sure on the code to make it max out, but I'm pretty sure that's what it is.
