The Black Lotus - Rift

[LiveForIt]

If it's all software rendered in real time then it's kinda impressive, although needing an 060 puts it out of the reach of the majority.
 
I didn't like the music or the style of the demo though & I'll be more impressed when someone does a c64 redux of it.

when some one makes a even lower resolution version of it that needs less CPU power.

C64 demos are extreme in that 100% optimized, some of demos will unroll loops while the demo runs, most of the tricks are done using translation tables, to avoid checks.

But lets say that 68060 demos are already using this tricks, then there is no way you can improve on it, unless you drop the fps.

That's the whole point of those demos. It wouldn't be impressive if it was just an animation

Maybe not, but even if it was I enjoy the music and art & firework a demo is.
More and more often I find my self just looking at demos on YouTube.
Is I'm NG users, it does make sense to run in on OS4, fake AGA modes are slow and does support 320x200 only 640x480, and can't run any of demos in EUAE, because EUAE PowerPC jit is limited to 68020.

anyway its not so impressive run the demo that was designed for 50Mhz on 1800Mhz, its bit silly :-D, anyway who cares, there is YouTube.
