I seem to be experience significant editor performance issues since upgrading to Windows 10. I am running Unity 5.2.3f1 64 bit, and whenever I create anything in the editor there is significant delay, and when I move anything around its very choppy, and there also seems to be dark artifacts that flash on the screen in various places, such as the editor, see here for reference. I seem to be able to play builds just fine, and I have 32gb bit of ram, so I am pretty sure it is not a resources issue.
It currently looks like unity is running dx11, but for some reason that is killing performance on my machine despite my dxdiag saying I have dx12 installed and supporting feature level 11.
If I add -force-d3d9 when running Unity and that has increased performance, but I still wonder why dx11 is operating so poorly.
From a reply of that post above, i found out it’s the Asus Sonic Studio caused the issue.
What works for me is delete that software and everything works fine again.
Do you use EVGA’s Precision X software to control your video card? I’m not sure about the flashing artifacts, but it’s been known to cause performance issues in Unity. See this thread for more info and a couple fixes if you use it:
If you have an MSI motherboard you may find that you have a ‘Nahimic’ icon in your system tray. Try and right-click and exit from this and then see if your problem persists.
