SM6 not available through DX12

Been having a nightmare setting up Unreal materials. So the card, GTX 1660 Super, I read supports SM6.5 but having just updated the driver to: 512.59-desktop-win10-win11-64bit-international-dch-whql (05-05-2022) and DXDiag is still reporting Feature Level 12_1, whereas SM6 equates to the “Feature level” defined by the capabilities of DirectX 12 hardware feature level 12_2.

Your driver then is up to date, Windows Device Manager is reporting the Driver Version as - how do I get to leverage SM6?

This doesn’t have anything to do with CUDA programming. I’m not sure what the right sub forum is exactly, but you’re less likely to find experts on this here. This might be a better forum. I can move your question there if you wish.

I thought as much - but maybe you could push through this reponse to your support team - as the forum location was specified by them - see below:
