Im currently running AMD-E350 1.6GHz Dual Core CPU, AMD Radeon HD 6310 4GB 'o RAM, Windows 7 Home Premium 64 bit, and Im getting 35-47 FPS on lowest settings, and about 27-30 on max, including shadows. Just dont record, you lose about 10-15 Frames.
Just thought I'd post this, so people know they can play with these specs.
