I cannot use any shaders in Lakka

Hi, can somebody help me? I use lakka on my RPi 3 and if want to use any of the shaders(including GLSLP) it will not be able to run or it will crash and corrupt the whole system. when i try to run psp games, they are very weird. ON te PSP, they are very nice graphics(like the GTA vice city one’s) but on the RPi, they are very bad.
