I hope this is of some help, I noticed one thing many of you have in common. Win8, DX11 and GTX900 series.

I'm using Win7, DX11 and GTX Titans in surround, nvidia driver version 347.52. Game works fine with detail (HBAO off, tessellation normal, shadows down) toned down in surround and in 1440P res, I can run it in max details, Here is a few thing I noticed.

It doesn't like Afterburner, I'm guessing it doesn't like EVGA Precision and the like either. Turn off !!

I tried using latest driver 353.30, ran horribly and crashed BSOD twice in 30 minutes. Use a older driver.

Turn off all overlay features if you are using display fusion, most games does not like overlay apart from Steam's.

DX9 runs fine in both window and fullscreen mode, DX11 however likes to run in fullscreen and actually performs better.
