3D in demos - F030 vs Amiga 1200

Is there any game that use bilitter for poly fill?

I only in resent years find someone blog that made study about blitter poly fill.

Relatively few. Hunter, F/A-18 Interceptor come to mind.

I would have to revist but im sure Fighter Bomber uses the blitter

What about Carrier Command?

not all demo are in real time.
it is if it starts soon when you click on the icon, but if it start after several seconds it precalcs.
In some demos you saw "pre-Calc" text (like phasetruce productions and others groups) while in the other you have to wait some times (when you think amiga freezed, the demo starts).

It doesn't have to be pre-calc though, not everyone liked the flashing colours while decrunching so it could also be that.

ArmourGeddon and its sequel did didn't they?

I checked Hunter by counting frames - it look like it is same speed as on ST.

Is there any other way to get FPS from video?

@kovacm
Also the polygon blitter article you mentioned, is it Scali's?

Yes, I became unsure about Hunter, too. It was from the impression I got back then. Since there's an ST port - it most likely uses the CPU.

Because the ST and Amiga 500 CPU frequency were so close, the games will have the same framerate.

If you play vector games on accelerator, the framerate might go up. If it's an 040/060, and it goes up a lot, the game is using the CPU for most things. If it just goes up a little, it could still be using the Blitter for most things. But it's a little bit up to the game design. And there could be an FPS cap in either case.

So framerate is not a reliable method, but if it goes up substantially on a fast accelerator, it can reveal which games used mostly CPU and didn't have an FPS cap.

Hello, I made a video today and I remember this old thread.

That's a whole load of awesomeness for one single desk!

[UberFreak]

That is a pointless comparison since the Amiga version is buggy and tuned for WinUAE, not real HW (according to the demo readme file).
It doesn't run smoothly even with faster clocked 060, is out-of-sync with the music on real HW and doesn't free memory when its done...
The Falcon version is apparently the "final", at least according to what I've read.

12 years later, I'm still waiting for a fixed version on the Amiga, but at this point it looks like that'll never happen

only 3D stuff - motion blur, transparency, textures... (super smooth, hi res)

Nice techno song at 40 seconds

Re: Starstruck

Since the Falcon in the video was 66 MHz and the A1200 was 50 MHz, it would only make sense that the Falcon would win. Not to mention the 5% penalty for c2p on the Amiga....

Ugh, just saw this.... First, if demos don't start immediately it doesn't mean they are not realtime, things can be decrunched before the demo starts! Also, precalculation doesn't necessarily mean demo is not realtime either! A lot of things can be precalculated (textures, (sine) tables etc. pp.) and the effects still are done in realtime!

Well the Falcon has to do c2p here too as it's still using an 8 bit screen.
Seems like the audio was offloaded to the DSP. The Ct60 has a more modern memory interface. Video RAM access is quicker on the Falcon too. It should be faster than a blizzard clock for clock. I wonder what a Supervidel version would have looked like. It has 1600 megabytes per second bandwidth to the video RAM. It also support 8 bit and 32 bit chunky modes. I wonder how a vampire would compare as well. I wonder how it would look on an Amiga reloaded too
