How's the UE 5.5 performance and stability for everyone?

[Yaklakootmaa2 (Yaklakootmaa)]

I have found the reason

UE 5.5 bad performance

Finally! I have found what causes this huge performance drop Disabling this option restores performance. Details The only open question that remains is why this option causes such a big problem on 5.5 UPD Forgot to turn-on weapon list widget, so the performance with it is this, 5.5 consumes even more memory Comparison

TLDR: Render to texture becomes much slower with no reason
