Are CLOUDS too heavy for performance?

or is there any REPLACEMENTS/ALTERNATIVES to it?

they are pretty laggy (on a normal baseplate i lose like 20-30 fps on high graphics when adding clouds) so you either use the laggy clouds or just put a skybox with clouds but they obviously wont look as good

Well they really aren’t heavy for me, and take into consideration that my laptop is trash.

Clouds are usually far away, so I would recommend making them just simple parts if you want to reduce lag.
