Flash running slow on Powerbook G4

Got a hold of an 550 MHz Apple Powerbook G4. But Flash 10 runs lousy on it. Frame rate slows right down and the whole machine chugs while Flash is running.

I found a couple of helpful articles on this.

I've uninstalled Flash 10. Installed Flash 9.0.47 (the non-universal binary) and it seems to have helped some.

It still doesn't run a YouTube video that great at all. The frame rate slows right down.

I upgraded the RAM from 512 to 768. The machine will handle 1GB so I'm going to fish around and try that upgrade next.

It's a shame. The machine runs pretty well otherwise.

Next step is a Flash 8 install. We'll see if that helps.

UPDATE:

Flash 8.0.42 seems to run pretty well. Going to try that. YouTube is still bad but slightly improved.

I'm hoping that the upgrade to 1 GB of RAM helps to get things into the clear a little more.

(BTW - this is a 550 MHz PowerBook 15" G4 machine on OS X 10.4.11)
