These kinds of shader filters require lots of GPU power. CPU speed is not important. Each pixel requires 10-1000 shader instructions (closer to 100 or even more with this shader), all pixels will be calculated 50 times/second.

Try commenting out oversampling, "#define OVERSAMPLE" -> "//#define OVERSAMPLE"

Another solution is the usual: Buy a better PC. (Or at least GPU)
