hi there,

EDIT: oh didnt see that there's a newer driver, installing 355.82 solved it...

I tried to run the DX12 hello window graphics sample (https://github.com/Microsoft/DirectX-Graphics-Samples/blob/master/Samples/D3D12HelloWorld/src/HelloWindow/D3D12HelloWindow.cpp), but I can only run it, if I set m_useWarpDevice to true, meaning I can only create a warp device.

I have a 64 bit windows 10 installed, I tried to run the sample on a gtx660 using the latest driver (353.62).

Nvidia control panel says I have dx12 runtime and api version, but only feature level 11_0.

DXDiag reports 11.3 directx version, and says that the driver is wddm 2.0 capable, but again, it only lists feature levels up to 11_0.

While I can still develop using a warp device, I'll need the hardware device later, so it'd be great if I could solve this

any idea how to fix this? I tried to reinstall the display driver previously, no success.

best regards,

Yours3!f
