Lag/Delay when switching compositions After Effects CC 2021

[thecr8tor]

Hi Community, slight issue here but I get a bit of delay/lag when switching compositions. The switch isn't instant. I only noticed it when I upgraded to AE CC 2021. Is there anything I can do to stop it?

Maybe you've set your render settings false

Heres a picture how to finde the settings, and now set it on Mercury GPU and not Software, sometimes its laggy if set on Software
