I was thinking it would be nice to have a list of the working retroarch shaders that have minimal to no performance loss in android. The ones that I have tested to work great are:
shadesr_glsl\scalenx\scale2x.glslp( works perfectly on snes cores, gba cores, sega cores, nes cores).
shaders_glsl/mudlord/sharpen.glslp (works great in pcsxr rearmed core and almost on every core)
shaders_glsl/retro/pixellate.glslp, sharp-bilinear.glslp, retro-v2.glslp, bead.glslp (work great on almost every core)
So what are your favorite retroarch shaders that work great on android?
Tested in archos gamepad 2.
