Troubleshooting Myst III: A follow-up

Regarding our previous report of problems with Myst III: Exile:

Skipping audio: a follow-up Tom Koons writes: "The problem with skipping audio on the PowerCenter computers is probably related to PCI timing issues on these computers. The 6400 has the same issue as those Power Computing systems are based on the 6400 mother board. Apple has a PCI timing update extension (see previous MacFixIt coverage) but it may not work. This audio skipping issue also gets worse with a G3 upgrade and a Rage 128 Video card. Most popular 3D games are affected."

Disc update only for PC users? Anthony Kassir writes: "I received an email from UbiSoft about some downloadable patches for Myst III, which are the first indication of what can be expected on the new Disk 1 CD. Unfortunately, all the patches seem to be for PCs (see this page). It seems likely, based on this and statements by UbiSoft Tech Support, that the Disk 1 replacement will be of no help to Mac users."

Virtual memory and QuickTime Mark Tuleweit had an assortment of problems with Myst III, running on his Power Mac G4 with 448MB of RAM and Mac OS 9.1. Symptoms included a double cursor, choppy video, crashes, and more. The cure for all the symptoms was to turn off virtual memory (despite UBiSoft's recommendation to the contrary) and downgrading from QuickTime 5 to version 4. [Note: our previous report had indicated that some problems were due to insufficient memory available to the game.]
