I know what dx 12 is, i'm asking how do I get the dx 12 version of the benchmark to run with my system, the dx 11 single thread and multithread works but stops working before the dx 12 benchmark starts. I'm running the latest windows 10 10041 with all the updates and driver version 349.90. cant seem to get it working.

Same Problem here. NV Controll Panel shoed dx12 and so DXDIAG. But NO Dx12 Test :(.

No SLI here :(

[LiLCLEMO]

have you got the latset build of windows 10.... make sure you are in the fast ring for updates too

[UL_Jarnis]

DX12 does not work with SLI yet. Or GSync. Or 3D Vision. Edit: Or ShadowPlay.

Also must have DX12 capable drivers - check DXDIAG that you have WDDM 2.0 and DDI: 12 shown. If not, your driver is not DX12 capable.

Recommended to get the driver to Windows 10 from Windows Update.

If unsure, uninstall NV Drivers, then run Windows Update and let it install drivers.

[LiLCLEMO]

you running the x64 version of windows 10?

[The Master]

Reinstall the Driver and now Dx12 :) Maybe a Bug from Update from old driver.

[Xcell Miguel]

Found it, disable ShadowPlay :)
