Because it's tracing rays, hehe! ;)
Yeah, it's logically rather heavy, since it does not only deal with pixmaps, but also renders accurate lighting with specular highlights on top of reading the image underneath at vector offsets.
In the last version I have an experimental check for FPS, should it go below 40 it switches to an image instead of the effect. Stupid, actually, since it may well go back and forth over the threshold, hehe... DUH! 8P
I'll fix it...
