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.

Although, on the real hardware that speccydemo is a flickering mess ;)


oh.. timing (made for spectrum clone). or a cheat (made for emulator?)

Nice work on your demo btw (as usual) :-) Cheers!

It's all interlaced to get more colors, the video is recorded from an emulator with a filter that blends two frames. Some parts look decent on the real hardware, but some have really shitty colorcombos (like flickering white and black to get a grey shade). The effects would've been a lot cooler with less colors and no flickering ;)

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...


Yes, seen for years on AGA and 030/50+, but can you say you've seen anything similar on OCS before?
