Hey so my editor is also running terribly slow. I’m trying to follow the steps in CyberGolem’s answer, but when I go to the Properties of the launcher.exe, first of all, ‘Target’ is not under ‘General’. So I go to ‘Shortcut>Target.’ I add “-DX12” to the end of the file path, and it doesn’t help. Infact, it makes the shortcut disappear from the start menu entirely. So I try to add it within the quotation marks, still not better. I’m not sure why adding " -DX12" to the target path would do anything anyway. Can anyone be more clear as to what exactly I need to change, or if there’s any other fix? Really need to be able to use UE4 again and cannot until it’s fixed.
