This triangle was rendered completely bare-bones, my own OS, my own GLSL compiler WHICH directly compiles to x86 machine code (was a pain, but using LLVM would be a shame to this project), and my own video driver of course.
This means there is 0 abstraction, my GLSL shaders now run directly on the CPU. Went from 10 to 40 fps for this one.
And yes, this is SWGL.
