Huge lag when smoke / semi-transparent / alpha effect

[[Unknown]]

Hmm, try unchecking "simulate block transfer" then? This will also disable a bunch of effects.

But if neither of those help, that's interesting. I don't own that game, so I don't know what effect it's using exactly.

If you're on Windows and want to dig into it a bit, try finding the fog with this:

Personally, I think you'll find it interesting to just see how the game draws things. Try to step until you see the clouds on the left side, and the area where the clouds end up highlighted in red. A screenshot of the debugger there would help me understand what effect it's using that's slow (you can post a link by not having http:// and splitting up the domain a bit, like "www google com /search".)

Also you can post links after some rules are met, maybe just a min # of posts. So maybe you will be able to now already.
