Screenshot of my engine software rendered, sutherland hodgman clipping still needs work, but fps is decent. Getting perspective correct texture mapping was a bit troublesome, you interpolate 1/w, u/w, and v/w, I was using 1/z, u/z, and v/z, which would have worked if I used the Z before perspective division, not after. (same goes for W, but after division it becomes 1.0, so pretty obvious) -- Updated from old screenshot that had z-buffer issues
