Hi all :)
Please post your results for the timedemo demo 2 in Quake2. I would like to know what the average is. An axample would be:
Amiga: A1200
Memory: 256Mb
Resolution: 640x480
Graphics Card: Voodoo5
68060: 50Mhz
PPC: 240Mhz
FPS: 16.4
And any other relevant info.
Thank you :)

PC: Celeron 2.4 GHz
Memory: 768 megs
Resolution: 1024*768
Graphics card: ATI Radeon 9200, PCI, 128 megs RAM
FPS: 300-ish
I had to! :-D
-
Is it the PCI-bus that is the bottleneck in your setup?
A 240 MHz 604e and a Voodoo 5 should be able to perform much better than that. My 120 MHz 486 gave better FPS than that! :-o
Is there any major performance difference between the old Permedia 2-based cards and the Voodoo cards?
-
That was just an example... :) and please stick with Amigas for this test :) :) :)

Oh, I know! I was just kidding. Anyway, I'd like to try the 68k version under WinUAE sometime, if possible (does it require an MMU?).
However, framerates are generally lower on Amiga games, even though the hardware is equivalent to the PC-hardware you compare it with. There has to be a bottleneck somewhere...

Sorry i misread the topic! I was referring to Quake 1 :-P

Amiga: WinUAE (see sig below for spec)
Memory: 138Mb
Resolution: 1024x768x32Bit
Graphics Card: WinUAE/Picasso96 32MB RTG RAM
68040: 1040Mhz (According to benchmark progs!)
FPS: 78.2 :-D

Hi whabang
long time no speak, dont get chance to sit there all day posting from work like i used to, remeber the long threads me u and red used to creat on out political discussions
hows tricks what u up to these days

@whabang
The lack of L2-cache on the PPC, and the 68k tripping it's feet once in a while are certainly not performance-booster.
And you still got some parts of the GFX-system running on 68k.
Bout PCI, the GRex SHOULD give the same bandwidth as PCI on a Pentium1/2, but the other solution are bound in via Z3 or some hacked up Z2 (the Z4-mediator and the ones on the trapdoor-slot).

If you are talking about MiniGL / W3D based Quake 2 (as distinct from the software renderer), some issues are
1) The gfx bus is a major bottleneck on almost all existing classic amiga PCI solutions. 10Mb/s is not especially good for shovelling large amounts of vertex data to the GPU. Most people have a mediator which in my experience peaks at about 13Mb/s for a good 060. PPC performance is likely not much higher.
2) Existing W3D drivers do not implement multitexture support. Quake engines really benefit from this since the environmental lighting is applied as a texture map. Hence, this ultimately requires two complete passes of a scene to render the textures and lighting.
Simply try "r_fullbright 1" to see how much faster you get without light mapping (consider that all the geometry transformation is supposedly done already and you are just retexturing an already calculated scene) to see the sort of improvements a genuine multitexture supported version could give.
3) A major improvement was added to Warp3D 4 in terms of vertex array rendering. If a MiniGL implementation doesn't make full use of this, relying instead on older v3 interfaces, you can expect a performance hit also.
In all, I think given the above, 16fps is not terrible. With multitexture support and optimal use of vertex arrays, double that ought to be feasabe.
-
might also be due to the Voodoo5 having to run in emulated Voodoo3 mode, as the 3D drivers don't support the Voodoo4/5's GFX chips directly, but as the board can run a cut down emulation of the Voodoo3's GFX chips.
you might find better performance with a true Voodoo3.

Timedemo 1 demomap demo1.dm2
Amiga: A1200
BPPC 266MHz + 68060 60MHz
258Mb Ram
Voodoo5500 64Mb
FastATA
IDE HardDisk
AmgaOS3.9
FPS = 17.4 at 640x480 16bit
PC: Athlon3000XP+ 2.17GHz
1.5Gb Ram
Radeon9700Pro 128Mb
ATA133 7200 Hard Disk
WinXP
FPS = 398+ at any OpenGL resolution 320x200 to 1600x1200
I think the hard disk has something to do with the performance too since the loading times are slower on miggy. Can anyone with a SCSI hard disk post the results?
Amiga rulez :)

You get about 26 fps with CSPPC233 and Voodoo3 (Prometheus bus); voodoo4/5 give about the same speed. With overclocking the card you may get a little more speed but the greatest bottleneck is the slow bus interface.
-
How fast do you get with lightmapping disabled? (to test it, use r_fullbright 1 in the game console)
-
@Karlos
r-fullbright 1 improved the framerate by 1.5fps so it's now upto 18.4 fps on A1200 Voodoo5 258Mb PPC 266MHz 060 60MHz...I know we can do better...just keep them coming ;)
Amiga Rulez!

JayJay! Nice to see ya! What have you been up to lately?
The political discussons are still here, allthough I rarely have time to participate theese days... :-D

had a bit of a mad last two years, got made redundant from a job i had for 6 years, started a long time realtionship (21months to date), out of work for 4 months, got a job as delivery driver, gave that up after 6 months, didnt work for another two, currently working for a car insurance compnay, got a dog(lurcher), currently moving house).

Hmm, I expected more. GLQuake 1 for instance runs about 60% faster on my machine with lightmapping disabled.

Not much.
Working my arse off, got downsized, got a new job at a warehouse, got tired of the new job, got a job as a fork-lift driver, got the sack as I didn't want to re-pack nicotine gums (Fuck Manpower! :-x), got a new job at a transport company, got my old job back at the call center, got tired of having two jobs, quit the night job. That's it! :-D
