Profiling the title at chappe388's 23 fps put a third of paint time in clipping and the garbage it allocates: every face built six arrays on the way to learning it was entirely on screen, every wall panel built four edge closures and three vector objects, every grass blade an array of edge pairs, and the flat floor ran two sines per probe to add zero. Plain-compare fast paths now answer the common case — a face whole in front of the lens and whole inside the guard band emits directly — and the clippers only walk for geometry that actually crosses a plane. Same pixels; a fifth off paint under V8, and the console's interpreter, which pays list price for every allocation, should keep more.
