Alchemy , ,

PixelBender ; ,

HaXe , 40% Vector

Nonstandard

methods:

Hardware acceleration only for PixelBender and not for every videocard

wmode = "gpu" slow

Alchemy big, complex structure, data transfer losses

PixelBender raster effects for small images, data transfer losses for mathematics, multithreading

HaXe undocumented memory managingmethods, faster up to 40% than Vector
