Hey I'm looking for a really expensive post processing technique that i can learn and implement in less than a week. It has to do with school, and after i find something expensive i have to optimize it.

So anyone know anything that will definitely cause a significant decrease in FPS?

Any kind of naive bloom/blur filter should be good enough. Try a 9x9 kernel, which - in the unoptimized case - will give you 81 texture accesses per pixel. If that doesn't bring your hardware to it's knees then ramp the kernel size up.

yeah i originally thought about blur, but i thought maybe something better was out there.

If you had a model renderered and a very basic g buffer you could analyze ssao. The many naive approaches are expensive with tons of optimization routes to research.

now that seems interesting

SSAO with bilateral blur should do it.

thanks for the suggestions guys. this should work perfectly

Add some Subpixel Morphological Antialiasing to the mix and voilá.
