Hollywood binaries working faster on G4 than on G5?

I bet it's the timing code itself. Remove it (GetTimer, StartTimer) and count seconds yourself.

I made some further tests now.

First your Hollywood code can be optimized to much faster, and when doing that, results are more in line with the CPU performance.

Wow. That's some improvement! Great work.
The trick with DisableLineHook() really seems to affect the overal performance... at least in current MorphOS version.

So basically you're saying that my (poorly optimized) code triggered some feature in MorphOS itself that dramatically cut the performance of G5 CPUs? And that feature has been somewhat fixed in 3.20?

@Georg: The timer is right. I sure can tell the difference between 14 and 24 seconds even without using a stopper watch.

You could not if for some reason the timer calls themselves were to delay execution several seconds ...
