Re: [glob2-devel] PerlinNoise based clouds

[Bradley Arsenault]

There is something odd about the new cloud implementation. Despite the
fact that I have no hardware gl (and GL is disabled) and no clouds,
the cloud drawing code still takes up an astonishing 15% of my
runtime. Just look:

It seems like, despite having Open GL disabled, the Perlin based
clouds are still attempted to be drawn, resulting in no clouds at all.
