Hello,
I didn´t found a topic like this, so I hope this is not a double. It is also just for feedback: I resently downloaded version 4.20 and it tells me to download older drivers for my graphics card because “there are known issues” with mine. [Uploaded picture] This is no problem that stops me working but I thought I should mention it.
I am running Unreal on Win10 + GTX1070. I hope that helps you!
