C64 coding - C64Ultimate Huge 3D speed improvement at 64MHz

Optimised 3D test on my new Commodore 64 Ultimate machine, running at 64MHz. I press fire to toggle between rendering one model and several models. Full source code and the PRG file are linked in the video description. This is a very quick test using some old 3D code. It's a lot faster than the stock C64 now.
