UNREAL ENGINE 5.4 EXTREMELY BAD PERFORMANCE

Hello , been using all the lastest features , nanites , lumen , reflection. My project has improved performance with 5.4.0 a lot . Just using a simple rolling ball , lots of chaos destruction, run wells in editor , loading time are faster . Very happy . It’s a very simple project . Ah tessellations crash but it’s experimental features so . Good luck to all
