I have 5750 with 10.2 and Win 7 7100 and I don`t think that I can run DX11 effects. I have tried Heaven with tessellation and the test comeup w/o it. I just installed AVP3 and I started the DX11 exe and in options there are no tessellation options. Same with Dirt2 I don`t think it runs in DX11 mod. How to make sure that I can run DX11 ? And if I`m not wrong about this how to make it work. Thanks.
