Hi, its exactly as it says, the option is greyed out on the client. I have tried installing dx runtime installer, checked net-framework 4 was working correctly and installed latest drivers for my system and GFX card. All appears to be ok, the card supports directx11 as far as i can tell. The only issue i can see is that i use 32bit system Windows 8.1 so im not getting the recommended 4gig ram. I am unsure if its the same on other games

Any other ideas?
Thanks
