After upgrading my GPU to a 9060XT when I hover the mouse pointer over some GUI elements the UE editor and launcher freeze for a few seconds.
This happens not only in the Editor itself but in the Launcher as well, when hovering over the listed projects.
It’s very annoying and honestly I can’t figure it out.
I am running UE 4.26.2, Windows 10, 4K resolution, Freesync ON, HDR ON, latest GPU drivers. When I swapped the graphic card I ran a DDU cleanup beforehand.
From what you are describing, I think the main conflict here is that your new GPU might be to new for your current setup. The 9060XT model is from last year, while UE 4.6 was released in 2020. Meaning, the engine won’t fully graps the GPU’s new architecture. I would suggest updating to at least UE 5.6, then test again.
Yet, if you need to keep your current setup, there are a few alternatives to test here:
Disable HDR and Freesync, as running them together is prone to generate frame skips
Force UE to launch with DX12 using the -dx12 flag on the shortcut
Use DDU to remove your current set of drivers, and roll back to an older set
