Overlay + Multiply Filter, very slow, can it be sped up?

[baka]

I use Direct2D
and I use overlays in my game. (60fps full animated, multiple layered game)
the overlays are used to create effects like darker, lighter, warmer, colder etc. but also shadowing.
thanks to The trick for this typelib.

and its ultrafast. I told u about Direct2D before.
so try it. quite easy to use.

and together with WIC, you have both loading and rendering.
and together with DirectSound, you have sound/music as well.

all 3 typelibs made by The trick.
just do a search and u will find it here.

that doesn't mean Cairo is bad.
for the cross-platform (in the future) maybe I will use that.
the importance is to be "smart" about it. use the best possible approach.
while in Direct2D you don't need to be that strict, since its gpu-based.
