* Better (and windows enabled) OpenMP handling (> 2x-5x speed) * More Volumetric Texture mapping options (heat, etc) <-- Matt if that's not to your liking, just revert that part, it's separate anyway * Initial velocity taken from particle settings (no more slow starting) * Option to select compression method (there seem to be a bug in my high compression usage, at least it's been reported to result in exploding smoke - better use low compression for the time being) It's been tested since a while but as usual please report any (new!) bugs. ;-)
