Does the Direct3D testing in DXDiag work with Win2K? I recently ran it and it passes the Direct3D test when using the DirectX 7 interface but fails when using the DirectX 8 interface with the followong error: Direct3D test results: Failure at step 5 (GetDeviceCaps): HRESULT = 0x8876086a (3D not available) I'm using the Nvidia reference drivers 28.32 and have also tried version 23.11. I have also reinstalled DirectX 8.1 numerous times during the test. I have the following hardware: EPoX EP-8K7A w/512mb RAM (not overclocked) Gainward Geforce3 Ti 200 (not overclocked during these tests) I tried playing Aliens vs Predator II (which requires DirectX 8) and it seems to play just fine. So I'm not sure if this is just a DxDiag problem or is my D3D8 really not functioning? Thanks for any help.
