graphics question

[chet david]

We discovered a mystery in the field of graphics performance. There is a Power Mac G3 and a Power Mac G4 in this scenario. The G3 is running Mac OS 10.3.9, and the G4 is running Mac OS 10.5.8. The G3 has a 64mb Radeon 7000 which can use Quartz by PCI extreme. The G4 has a 256mb GeForce 6200 which naively supports both Quartz Extreme and Core Image by hardware. The G3 seems to be having much better GUI performance with Expose and genie effect. What give?

naively supports

What a silly card!

Anyways, I can't really help but if you have the time maybe you can reinstall the OS. Then you can compare see if it's a panther vs. leopard issue.

the geforce is almost a couple generations ahead in technology (lets say a ati7000 is about in the same range of a middle end geforce 2 give or take technology wise, I used to have a 7550 and it would routinely get handed by my geforce 2 gts)

10.5 has considerably higher graphical requirements than 10.3, which only does the basics. As 10.5 places greater reliance on the GPU - in this case a lowly 6200 (which is a PC-flashed card is 64-bit), running Core Image, it will seem a little slower. However, in theory it places less load on the CPU which even things about, the the 6200 while a little sluggish with some desktop operations is quite decent for most things.

my bad I misread the op

10.5 does not exactly run nicely on a G4 either.

I find 10.5 runs quite well on my MDD.

MacJunky, what are your G4's specs? Remember, dependence on virtual memory will slow anyone down, especially if the hard drive is slower and particularly with Leopard--the enhanced graphics are a definite RAM hog. Max out your RAM to 1.5 or 2GB, and don't attempt Leopard on a Yikes–1GB and a slower processor will drag it down.

1GHz 7455 Digital Audio, 1.25GB RAM, GeForce 6200 256MB, 500GB 7200RPM SATA HDD(bootdrive/onlydrive), USB 2.0, 350W Seasonic PSU. It is not exactly spectacular, but it is not terrible for a G4.http://poopr.org/images/2oyqf59zfkrtdsq7gafb.jpg

(yes, I know the case is a little big for what i have in there and that the CPU fan is not properly mounted, I want to get another case and mount a different heatsink sometime )

I am just spoiled by having used OS X on a 3.2GHz dual core w/2GB and 3.0GHz quad core w/4GB with modernish Radeon gfx card. Again, not the best and kinda old, but not slow. And both certainly spank most of the real Macs that most normal people use at the moment.

Anyway, back on topic.

Most people do not have loaded dual 1.42GHz MDD systems.

I still am just surprised that a 64mb Radeon 7000 PCI card does the same exposé effects better than 256mb GeForce 6200 AGP card despite different OS.
