See, the game generates clouds by sampling each pixel and make into a single cube; with many pixels on the cloud's texture, there are cloud faces inside clouds that you can't see from the outside, as the screenshot below provides.
(The cloud is bigger than what you see from the inside.)
So I think removing clouds inside faces would increase quite an amount of FPS and unobstruct the vision inside the clouds.
