I currently run AC on Windows SP3, With 512mb RAM and a 1.2Ghz Processor WITH a Nvidia GeForce FX5500. On most maps I get 60-100 FPS with graphics set to medium, The only time I've had this problem is when I had a virus/Mal-ware or anything hogging the CPU. Check your processes for anything that looks suspicious (Anything using a massive amount of ram, or hogging the CPU). The only other thing I can think of is checking your drivers to make sure you have the correct ones installed, and I know for the video card I have on their site there was an option to download a "suite" which you can launch via your control panel and tweak the video card settings around a bit. Hope you fix your problem.
