First of all, the auto detect is broken and always has been. Ignore it. Secondly the EE patch has a major performance issue that they won't even acknowledge and others on the official forum just give generic copy/paste answers. My rig: i5 2500k @ 3.9GHz 8GB RAM 2x AMD HD6870 (CrossFire) Before EE patch, all settings Ultra with UberSampling disabled = solid 60FPS After EE patch, all settings Ultra with UberSampling disabled = 20-30FPS Changing resolution makes no difference, setting everything to LOW makes no difference, turning off Xfire makes no difference. I can run Metro 2033 and Battlefield 3 at max settings with 2xMSaa at 60fps. My computer is a beast. Their game is broken.
