quick question... I have a ASUS ATI Radeon 5870 GPU... and I was running DX11 before I reinstalled my vista64.. now after the (clean) installation of vista64... I can't seem to get the DX11 working again... it only show up as DX10 (Despite several brave attempt to reinastall the catalyst and drivers)
Is this cause by me not having properly upgraded to vista 64 Service pack 2? as I did run into some problem upgrading windows to SP2??
More aboutdoes dx11 require vista
yeah just get sp2 and get all updates, then you'll have dx11. atleast i do
