The 1980s computer produces surprisingly gorgeous ray-traced results, but be prepared to measure performance by hour rather than second.

    The human eye can only see 1 frame per 18 hours so I consider this reasonably fast.

    i once took 12+ hours to raytrace on an 8mhz Amiga only to realize that it didn’t have any light sources and so was pitch black.

      You could get a totally playable fps if you play in geological time scale

      Edit. Not really fpS as s stands for second, but …

    700 years worth of compute to do about an hour of gaming that I just did on my pc at home in realtime … damn.

    Did I math it right? I was averaging about 100 fps in hogwarts for about an hour.

      Say you generated 86’400’000 frames. 17h a frame that’s roughly 16’767 years.

    I mean that’s pretty fucking impressive imo. I figured a RT frame would take days to render on hardware that old

      And back when that computer was contemporary, it would have. We’ve learned a hell of a lot since Nvidia announced they had cracked real-time ray tracing all those years ago.

    Now write it in Z80 assembly instead of basic and see how much faster you can get it to run.

      So true.

      When I switched from basic to assembler on a Trash 80 Model 1, it was truly night and day
