Not all actors unloaded from memory with "Actor Hidden in Game"?

During render some actors are unloaded from memory on “Actor Hidden in Game” and some are not? E.g. hiding Geometry cache seems to unload it from memory but hiding static mesh does nothing. Is there a way to force unload them from VRAM when they are no longer used?

destory them.and make sure there are no actors are referencing them

How do I destroy actors? Is it available from UI?

sorry,I didn’t notice you were talking about VRAM,I thought it was RAM.

I don’t know much about that.
perhaps someone else knows it could help. :grimacing:

Anyways, what’s “destroy actors” option? Even if it will help unloading them from RAM it still would be useful.
