Well I decided to see what graphics card I've been using and as it turns out, I don't have one (0_o) instead I have the "Intel(R) G33/G31 Express Chipset Family" which according to the sites I've checked isn't even a proper graphics card, just built in display adaptors so I can have a monitor and such installed. As far as what I can and can't run, Diablo 2 is fine, TF2 however, has an FPS of 00.05
