Some people tried to tell me that PICO-8 runs as fast as a host machine does (which, as we all know, is not true).
So I created this little "benchmark" cart with a roto-zoomer effect running in 60FPS. Use up/down keys to change the filled area of a screen. On my computer (MacBook Pro 2017) it consumes 98.2361% of PICO-8 CPU time at 47 lines.
My friends and I created a new demoscene production for PICO-8 — PICOCHAK. It was first presented yesterday at CAFe'2019 demoparty. It took 2nd place in Console Demo Compo.
