Hi, I’m having a very similar problem with the Unreal editor being weirdly laggy for example whenever I hover over tabs like file edit tools etc. From other threads and posts about similar issues I found out that when I have my editor on windowed mode the problem simingly disappears. I have also seen a pattern with most people having this problem have amd graphics cards. The thing is the editor was working fine before for me with fullscreen aswell, but I upgraded my CPU (along with new ram and mobo and m2 ssd) and I also fresh installed windows and everything. After that both 5.3 from the epic store and 4.25 from source are laggy af in fullscreen with 5.3 even crashing. Things I’ve tried so far is: Updating my drivers, playing with multiple graphics card settings and especially vsync and also trying settings in the editor such as the ones suggested above…
My specs are:
Ryzen 5 5600
Radeon 6700XT
32 GB Ram
Any ideas? For now I just opt out of full screen and resize the editor to cover the whole screen but still sometimes there is a weird flashing here and there
