Nope, on my 1.42ghz mac mini even stuff like Aladdin isnt quite perfect (although its pretty close). Having said that though Ive not spend much time fine tuning euae config, so there's probably a little more juice that can be squeezed. From my experiences with it on othr systems, and the difference a bit of tuning can make Id hazzard a guess it could be maybe 10-20% either side of a stock a1200 without fastram (depending on the game).

Big difference between a similarly specced G4 vs. an x86 system with euae (favoring x86 of course). Hopefully this will change eventually, but if the "progress" reported thus far for the ppc jit 68k emulator is anything to go by I wouldnt hold my breath unfortunately.

It's of no real consequence to me really. My a1200+'040 card keeps me pretty content for custom chipset hitting software. The main reason I even set up UAE on any of my systems is for the sake of "completion" (especially true with my amithlon box being that its OS3.x based it just "feels" right to have access to any classic software), plus depending on what Im doing its not always practical and/or worth the effort to switch machines.

A 320x256x8 screenmode makes quite a difference to speed I must admit, but then things dont look quite right (ditherig and/or wrong colors for example). It also requires a little luck as far as monitor/gfx card goes to even be able to create it.

To each his own, but if something doesnt work full speed, full framerate its not worth the effort in my opinion (although I guess its easier to think like that when I have an ok-ish real amiga as well).

Can someone please tell me whats the fastest supported powermac g4 you can get that is supported by morphos...?

I guess that a MDD with an accelerator. Despiting having slower memory it seems that most fastest G4 cpu cards are available for QuickSilvers. But anyway I think that MDDs are the best ones. There are accelerators running at 1.8-2Ghz from various companies like Sonnet, Powerlogix and others. Some of them have a 7448 and I guess that's the fastest. Perhaps it's possible to overclock bus speed a little with MDD if you install a 7448 (it admits up to 200Mhz bus frequency)

I have played 1920x1080 videos on my Mac Mini but audio lags behind , it depends a lot on the codec used (for 1920x1080 I tried using mpeg2 iirc, although 1280x720p using h264 work without problems)

Also, I'm sure I saw someone here talk about a processor upgrade to 2ghz+ he got that he used on his morphos machine. Any info on those/links would be appreciated.

It's probably a quicksilver with a 7448 2Ghz cpu card. But Quicksilver uses 133Mhz bus instead of 166Mhz so I'm not sure if performance is much better than an MDD. I guess that an MDD with an overlclocked 7448 running at >2Ghz should be the fastest.

In searching ebay, I am finding tons of 800mhz-1.25ghz g4's but none much faster...

Get a MDD one. You may have to seek a cpu card separately. These aren't common but IMHO these are easier to get than working CSPPC

And can someone tell me at 1.25ghz can you run very demanding aga games in uae in morphos without any lag?

I haven't tried AGA games. I have tried A500 demos and these seem to work without any frameskip at full speed on my Mac Mini. I even use hi-res and don't use lo-res so I'm sure A1200 games should play ok if you set the screen to lo-res. You should use the native version with Overlay and avoid using the SDL one, after all RTG-compatible apps should run natively on MorphOS directly.

Can't do that on 1.25ghz-2ghz intel or amd pc, with winuae without lag city (at least for very demanding 68k games)  but I don't know much about g4 or mac hardware in general.

What do you mean by "very demanding games"? FPS games could run on MorphOS if RTG is supported. I guess Doom or Quake doesn't concern you, right?

I just don't want to buy one then go gee its not fast enough and have to buy another one.

Any thoughts very appreciated...

You can always buy a cheap MDD 1.25Ghz or 1.42Ghz, test it with the demo and see if it suits your needs. If it doesn't you can sell it for the same you paid. If you like it you can buy the MorphOS license.


PS: if you are interested on laptops you may check out a powerbook as it has a 1.67ghz G4 and a fast gfx card.

Being that Im a bit of a perfectionist and things running properly is a bit of a concern of mine Id hazzard a guess Haywirepc mean things like Xtreme Racing, capital punishment, Tzero, Super Stardust, AlienBreed3d, scene demos and so on. With emulation "heavy" games arent always ones that require more resources on thier native machne, a leason that has cost me quite a few upgrades over the years
It's more about knowing that everything's fine should I decide I want to use "Software X" than particularly wanting to use it

@Fab
Id be interested in any feedback or suggestions you could give me though when you do get around to it. Im pretty new to MOS and its different versions of software, tweaks and so on and Id be a happy man if I could get a little more performance out of euae for when I want to use it.

First tell me which UAE port you use. I suggest you use mine (WIP3 or 4) at http://fabportnawak.free.fr/uae/

For speed reasons, the uae binary should be used, and not the uae.sdl one. In the config file, you can enable overlay by using amiga.use_overlay=true (it's shown in the config files supplied in the archive).

As crumb said, the fastest you'll probably find is an MDD Power Mac G4 (uses DDR RAM; I read that the G4 doesn't have a DDR-capable bus, but that's still faster than PC133 SDRAM) plus one of the third-party accelerator cards (which go up to 2GHz.) Those, however, can be pretty pricy. You may find it cheaper and easier to get one of the 1.67GHz PowerBooks - I haven't tried much in E-UAE on mine, but in other demanding applications (Flash video) I've found it quite a bit snappier than the 1.25GHz G4 machines.

Okay, from a quick test on my PowerBook, with E-UAE set for an AGA 040 with most-accurate emulation and zero frameskip, Aladdin runs pretty well. I don't have the original as a basis for comparison, but it's smooth enough that I can believe the bottleneck is in the emulated hardware.
