Hi, I have an AMD Radeon HD 6670 Graphics card and everything works fine except I can't run anything that requires DirectX9 3D 32 bit mode.

When I run dxDiag, all three displays say Direct3D Acceleration not available, however when I click the Run 64 bit DxDiag, all acceleration is enabled.

All other graphics functions seem to function normally.

I was directed here from a helpful person in the Microsoft forum:

Additional Details

I've searched around, ensured drivers were up to date, and treaked some settings that were reported to help problem, no success so far...

Any Ideas about what the problem actually is, and if there is a fix or a graphics card that wouldn't cause this problem?

Thanks, Sue

a 6760 or a 6670?...im assuming not the same thing

"I can't run anything that requires DirectX9 3D 32 bit mode."

are you saying you cant run a Dx9 32 bit game? any game?  what happens when you do?

im not sure, i must be confused.  i think i would install proper drivers, DX and GPU or possibly scan for virus dealing with .dlls?  sorry but i dont get the post...

however, if you have win 7 with 6.... something and cant run a DX9 32 bit application you must have a problem..

DX9 games can benefit from having 'enable surface format optimizations' enabled....in the CCC.
