iMac Problem

[Biggles194]

Why does CM run extremely well on my son's iMac 233 at minimum memory (35MB) yet on my iMac 400 SE DV it crashes and frezzes evert time I play. I have tried every memory setting from min to max. Any suggestions?

Make sure you have OpenGL 1.12 or higher, and that you run the game at no higher then 800x600 resolution.

1024x768 is too much for the 8MB VRAM of your iMac DV and the game will drop out when the 3D portion of the game loads up.

Thanks Gyrene but both machines have 1.12 OpenGL and are running at 800x600! There must be some fundamental difference between my son's RevB and my revD, is the ATI card the same?

Biggles, you probably have an extension conflict of some sort.

Do you have a Rev D (333mhz, tray loader) or a 400mhz DV?

Go to the extension manager (Apple menu > Control Panels) and select MacOS Base then reboot your computer.

The Base set *should* have everything you need to run CM, if you have a mouse that requires a custom driver, I'd use the stock Apple mouse for this test.

If you can run the game without crashing then one of the extensions that was turned off is at fault.

From this point on it's trial and error, you can work with the "Halves" method to isolate the culprit extension:

-Select half of the extensions that were turned off and turn them on.

-Reboot and try game

-If it runs fine then the trouble is in the other half - Use the half method on the remaining extensions.

-If it crashes on the first half, then half it now until you isolate the culprit. Also, test other half of the original turned off extensions, just in case.

If you need help identifying extentions get Extension Overload from Versiontracker.com, it gives you a lot more info on system extensions that Apple's manager does.

If this doesn't solve your problem, then we'll take it from there.

Thanks again Gyrene, I have a 400 DV SE. I'll try the extensions thing and let you know, Cheers
