What is the real power of Akiko chip in cd32 ?

[steveuk]

There's a project here for someone... Doom on a stock CD32!

working on it :laugh1:

Fantastic!!!

[skolman]

I could try that, but I am just too lazy.

Tests can be done TimeC2P with GloomC2P10,
newer c2p are the latest versions of Gloom.

Example CLI: TimeC2P akiko_1 1

[skolman]

TimeC2P Gloom 1x1 256 colors

68020/14 - 61.6 ms
68020/14+fast - 54.6 ms
68020/14+akiko - 24.2 ms
68030/50+fast - 21.7 ms
68040/25+fast - 18.6 ms
68020/14+fast+akiko - 17.6 ms

Heart Of The Alien Redux Amiga v1.0 - Another World sequel as an Amiga port gets an Amiga CD32 beta release

"The game uses C2P for rendering so we've been testing builds using the Akiko for that, and we've seen a big FPS increase. Currently with the test build, cutscenes can still drop down to 50% framerate but ingame framerate is either at or close to 100%."

Would be too slow on a 14mhz '020, even with RTG.
Even disregarding c2p overheads that spec system, with 2meg RAM can barely play Gloom well let alone Doom.

Yep I agree but I think Wolfy is possible

[fishy_fiz]

Yeah, definitely. Runs ok-ish on an 8mhz 68000 Atari ST, so an optimally tuned version for CD32 should run quite well.

Just looking at specs needed for original dos versions of these games gives a pretty good indication.
CD32 is, in raw grunt terms, well short of a 33mhz 386, and Doom, even with 4meg RAM runs terrible on that sort of system. And that's a machine that is optimal for that style game.
Wolf3d on the other hand runs OK on a 16mhz 286, which a 14mhz '020 can comfortably match.

Question, what will be the result on sx32pro 68030/50+fast+akiko?

You can see that you never use the Amiga. You're just a collector.

Tests can be done TimeC2P with GloomC2P10,

LOL no one else has CD32 with 68030?

Neat. Always nice to have another CD32 title.

Yeah, I "collected" the SX32 Pro back when it was new, from DCE. I use it a whole lot, but not for games (SX32 Pro was not made for gaming), and I don't have Gloom.

Yeah, I've got an SX1, but I'd kill for an SX32.
And I'm wouldn't be using that for games either.

The SX32 Pro is an equivalent of an A1200 with 030 accelerator,extra memory, hard drive and CD-ROM. I don't remember A1200 owners being so precious about only using their 030 machines for productivity! Get off your high horse. Just because it is rare doesn't mean someone shouldn't play a few games on it every so often:

Genetic Species
Alien Breed 3D
ADoom
TFX
Heck even Theme Park benefits from a 030 and extra memory!

All worthwhile uses for a CD32 SX32 Pro if you can find one ;-)

[Oldsmobile_Mike]

ADoom

Not to change the subject too much, but I have both ADoom and DoomAttack on my A2000.  Of the two I found DoomAttack to be faster and have more features.  Obviously just IMHO, but if you haven't tried it I'd recommend it:

You have a yellow papers? TimeC2P is not a game.

How about grow up and realize some people actually use their computers for something productive?

Hi Nova
I have been following this thread and wondered why Doom was extremely playable on Jaguar as that was only 2MB. I know Jag had 26mhz processor and CD32 14mhz - however i have played Doom Attack on CD32+4mb and it plays ok.

I am of course not a programmer or developer so my knowledge is limited - is it because it was developed by John Romero himself especially for Jaguar? Could a hacked down version by do-able on CD32 even if it has less colours or stripped down Graphics?

Would you be willing of having a crack at this if i paid you for it?

Thanks
Steve
ps> Wolf being made i believe at the moment on Jag by the same guy that did catacomb 3d.
