RoomBox Library - extremally slow?!

Please solve this issue…why Custom Library / Import Map works so slow??
Clicking arrows - slow and annoying, waiting for previews…too slow!

Solve this on the next update, pls.


What are your computer specifications? (CPU, RAM, GPU, etc)

Your computer should be able to handle RoomBox very well, this is strange.

Does the same happen with other extensions?
