Amiga OCS Demo Won at Assembly 2010 Demoparty

That's awesome. For those that aren't able to view it properly, there's a youtube vid:

As good as the demo is, the competition rules are pretty skewed if 486 machines can enter and an 040 and/or AGA based amiga can't, IMHO.

No I think they have got it abour right...

What, 1992 era technology not oldskool enough? It's 2010. If my A1200 were a person, it would be old enough to vote (at least in the UK) by now

[Karlos]

I dunno, I mean it's totally out of order that the speccy is expected to compete with 32-bit machines, IMO

The "midskool" idea is probably fairest, I reckon. Perhaps:

386 - 586 (< 100MHz), up to VGA
030 - 060 (< 100MHz), up to AGA

"oldskool" could then be something like this:

086 - 286 (< 20MHz), up to VGA
000 - 020 (< 20MHz), up to AGA

"proper oldskool" would then be everything sub 16-bit era

I wasn't impressed by the demo... And still the same 2x (160x120, doubled) pixels in most scenes we have seen for years... This is ugly...

Meh. What do you want from a 25MHz 030 ECS machine? Regular lo-res would quadruple the number of pixels to calculate in what looked like a fundamentally 3D demo.

To be honest, some parts could probably have used a better resolution. But as I didn't have a A3000 to test it on myself (only an AGA-machine with faster memory and 030/50MHz), I didn't want to take the risk of the framerate dropping too much. The 4bpl c2p-routines could probably be made faster, so maybe next time I'll try to do something in a higher resolution

I actually thought it looked fine, despite the 160x120 resolution. Human eyes are more concerned with motion than they are high detail, so fluidity is better than sharpness if you have to choose.

What is copyspeed on the A3000 chip RAM anyway? There comes a point when your C2P is no longer the limiting factor, though I usually found that was into 68040 territory for AGA.
