How to upgrade from DX10 to DX11

You look to be win 7 and with that card should be DirectX 11.

interestingly - I did same check and that display on my comp shows DX10.... however, its DX11
Check yours.....

Press Start - and in the "search programs and files" bit type dxdiag.exe
run that and see what it says

Dxdiag is the microsoft Directx tool .... mine shows that my sys is running DirectX 11 and I suspect yours will to.

HTH
Cheers
