integrated video, but that shouldn't matter as I play other much heavier games with heavier shaders, it should work.
How heavy the shader is doesn't matter, what matters is the computer's ability to parse the shader instructions... I have no clue how you play any game with integrated graphics... that is admirable... but I take that whatever the instruction is that is causing the error comes from the fact... that maybe one of those instructions is more modern? that is my only guess...
