So, I don't know if someone has already found this trick to increase fps with AMD Crossfire. Normaly second GPU won't work with Crossfire, but if you rename "TESV.EXE" to "Crysis2.EXE" IT WORKS!!! I have just little problem, SKSE searches for "TESV.EXE" so it won't work with this fix. If somebody knows how to make SKSE search for "Crysis2.EXE" I would love to hear that. My poor PC specs: CPU AMD A6-3410mx OC 2.6GHz, GPU AMD Radeon HD 6520G and 6750m, RAM 8gb.
