UE5 - I need your help guys

Development Getting Started & Setup
1

when I play the level in a new window (PIE)
the Metahuman character is moving his face with my motions very good, but when I click in any window other than the PIE window it starts to lag. and when I click again on the PIE window, the character moves normally !

what should I do ?

Lower quality of metahuman (you probably imported it at max quality). Or get better (nasa) desktop PC.

You can also keep suffering or not click other tabs.

But my bet is: reimport metahuman at sane level of quality.
