Genshin Impact — Mouse input lag only in fullscreen

Quick one for the people who have put more hours into this than me. It seems to depend heavily on region, which nobody mentions anywhere.

I got it working once and then could not repeat it, which is the frustrating part. Curious whether that matches what everyone else is seeing.

Same boat here. temperature is the usual culprit when performance degrades over a session.

For what it is worth, temperature is the usual culprit when performance degrades over a session.

Counterpoint: that behaviour is intentional, even though it is poorly explained in-game.
