How fast is Grannys texture decompression?
Granny’s texture compression is based on Bink Video’s image compression algorithms, which by necessity must perform very quickly in order to maintain high framerate video playback. The image compression gets similar compression ratios as JPEG 2000, but performs at several times the speed. However, it obviously is not quite as fast as simpler compression schemes such as S3TC which do not compress the textures very much in the first place.
