SilverLining 2.30 is now available from our download page. In addition to several bug fixes and better compatibility with a wider range of graphics cards, it also includes substantial performance improvements for cumulus cloud types. In addition to being about twice as fast as in previous versions, our GPU ray-casted volumetric  stratocumulus clouds are also much more realistically lit and are rendered with higher quality. This higher quality has also reduced sampling artifacts in stratocumulus clouds, but if you still see any, try increasing the MAX_SAMPLES setting defined at the top of the stratocumulus fragment shaders in the resources/shaders directory. Visit our gallery to view some new screenshots of stratocumulus clouds in SilverLining 2.30.
