[Nai no Kami]

I have posted this in the OSX forum, but nobody seemed to read/reply to my request. I am really interested to know if I am the only one with this concerns. So here it goes:
I have an original iBook and I realized that Open GL applications just run terrible (I mean TERRIBLE). I could run, say Gl Tron and VirtualWings Pro with OS 9 (which proves it is not the machine's fault) at more than decent speeds. Now, running this programs from classic or in their native versions (this is the case of GL Tron) is almost impossible. I also found that running "Snoopy vs. Red Baron" (a 2D silly game available from Versiontracker) with GL acceleration is like moving under water (or under styling gel) whereas turning GL off makes it decently playable. Making tests with other classic apps that used to run fine, such as Pixels 3D, showed that reiggering a quick render gave a blank screen as a result. Another curious thing is that other 2D games such as Reckless Drivin' run fine.
What is going on?. I assume that neither 2D nor 3D accel are currently supported. Then I wondered: which graphics card does the iBook Bare. System Profiled did not tell me wether it is a rage 128 or rage pro based mobility chip.
Please someone enlighten me. Thanks.

The original iBook had a 4 MB RAGE Mobility card (2x AGP).

One of the things to consider is that OpenGL takes a lot of RAM to run correctly. You didn't say how much RAM your iBook has, so that could be considered the culprit.

Another possiblity is that the drivers for the RAGE Mobility (and specifically for OpenGL) aren't optimized as they could be for OS X and the iBook.

If you can afford to, try adding more RAM. If not, hang out at Accelerate Your Mac. Occasionally, someone from ATI posts there discussing driver updates and stuff. You may get an idea of what's going on and whether or not it's an iBook problem or a driver issue.

the iBook 2000 with firewire shipped with the ATI Rage Mobility 128 in a 2X AGP slot
