I have gtx 760 in sli, I want to know if metro 2033 REDUX version support sli? I ask this because i only get about 23fps in 1080p at max settings with saa 4 and without physx or tesselation. I dont think this is normal given that in metro last light with same settings I get 30fps which is at least playable and it should be expected from 760sli. Is there some way to fix this problem with metro 2033?
