Skydome mesh low FPS

I have a project, i believe it started with the time of day template.

I am new to unreal and just started learning about optimization.

Turning off the skydomemesh increases the FPS by 30 - 60%, is this right?!

Is it really that hungry in terms of power or am i doing something wrong - these settings were standard.

GPU is 2080ti

Appreciate any direction on this - any tips, i like clouds, but that performance is a huge hit

30-60% really means nothing without the actual numbers. More specifically how much ms is skydome taking to render?

Super old post but i’m having the same issue.

Skydome is costing me 10fps in editor.
