Since yesterday, LOTRO through Steam is unplayable slow, even when loading the game.

I can't figure out a depository update that could have an impact on that.

Using different Proton builds doesn't change anything.

Anyone else having issues with Steamplay?

It has been working flawlessly, since i moved from Windows to Linux approx. 2 months ago.

EDIT:
I am running Pop!OS with the current Nvidia drivers.
