Folks.. I was trying to play Metro 2033 with my Eyefinity setup at 5760 x 1080 which i have 2x5850's on a i7-930 platform on 10.9 driver/profile.. if i set it to DX 11 with normal settings then it shutters at like 1 fps .. but if i set it to DX 9 it plays fine under the same settings.. to i need to drop it to low setting in DX 11 ??
