Slow or frozen graphics are most often caused by low video resources. The best way to improve performance is to complete ALL of the following steps:
First switch your color resolution from millions to thousands of colors.
If your display colors are already set to thousands of colors then check the "Economize video memory" checkbox in the Marine Aquarium preferences. If you are trying to drive multiple monitors from one video card then both steps may be necessary.
Go to the Marine Aquarium Settings menu and reduce the "Shimmer" setting.
Also, turn off the bubble column and reduce the number of fish.
Lastly, set your Apple Extension settings back to the OS9 defaults. Click on the Apple Menu, select "Control Panels" then "Extension Manager". At the top of the menu, choose "Mac OS 9.x All"
After finishing all of these steps, take each setting back to default to see where the problem is solved.
Freezing problems have been known to occur on the iMac DV. Our program does not cause this problem, it happens to many 3D products. It appears to be a problem in the Rage128VR chipset. Apple is researching the problem.
If none of the above fixes work for you, please e-mail
us and include the Frames Per Second that the Marine Aquarium is running at (This can be found by pressing the "S" key while the program is running.) and an OS9 Apple System Report (ASP):
Open Apple System Profiler, select File/New Report.
Select the standard System Profile, and "Devices and Volumes" and "Extensions".
Save the report to a file.
Compress it with stuffit or some other common compression tool.
E-mail the System Profile to us with a description of your problem.
