I recently, upgraded my Windows 10 from version 1703 to 1709, and what I noticed, is lot of my existing games do not run any more on it.
I do have another system with Windows 10 with version 1703 and the games run absolutely fine.
Both the versions have DirectX 12.
My Video card is GTX 970 and video drivers are updated. So not sure what the Fall Creator Update (ver. 1709) changed in my system.
Company of Heroes II launches with error : Failed to find supported hardware rendering device. Verify that DirectX is properly installed & that you have the latest drivers for your system.
