Hello, I recently installed Arma II: CO on my iMac via Boot Camp, and my frame rate is way below expected (20-25 on minimum settings). I'm really a noob at determining the quality of the parts of the computer, so could anyone help me out? System: Intel Core 2Duo E7600 (3.06GHz) 8g RAM DirectX 11 NVIDIA GeForce 9400 Could anyone help identify the problem?
