I've never bothered/been able to work out using Pixel Bender shaders. From what I had heard is that they aren't THAT much faster, though I should try it out to see if it's faster than my current lighting engine...
I did some comparisons between normal filters and Pixel Bender shaders and they run quite a bit faster.
(I had to use a friend's computer to test because my computer doesn't lag no matter how hard I strain it.)
Effect Type -- Average FPS out of 30 Possible
Color Shifting (Flash) -- 25/30FPS
Color Shifting (PB) -- 30/30FPS
Pixelation (Flash) -- 23/30FPS
PIxelation (PB) -- 30/30FPS
Simple Blur (Flash) -- 23/30FPS
Simple Blur (PB) -- 30/30FPS
Color Shifting, Pixelation, and Simple Blurring (Flash) -- 13/30FPS
Color Shifting, Pixelation, and Simple Blurring (PB) -- 30/30FPS
Memory usage is high for PB shaders but the performance boost is worth it.
