I found some workarounds (at least for my 1.5Ghz G4, 1GB ram, with Leopard 10.5.8)
Install a G4 Optimized version of one of these browsers:
Optimized Firefox 3.6.3 for G4
and/or
Optimized Camino 2.0.2 for G4
Install Flash 10.0.4
- many people are saying that Flash 10 is too slow, but you need it to run latest web apps, Hulu, or to watch HD videos - there is little choice here, but its ok because it should still work for most 1Ghz+ powerbooks
Launch any flash video (YouTube, Hulu, etc.).
When the video comes up right click on it, you should see a Flash Plugin Menu. Go into:
- settings: enable hardware acceleration (disable it if it causes problems)
- settings: increase storage limit to 10MB
- quality: set to Medium or Low (depending on your system)
Change your computer power settings:
Make sure power is set to "Normal" or "Better Performance". If set to "Battery Energy Savings" videos can still get a little slow.
My configuration:
1.5Ghz G4, 1GB ram, with Leopard 10.5.8
G4 Optimized Firefox 3.6.3
Flash 10.0.4 (quality medium, enabled hardware acceleration, 10MB storage)
(computer power setting on "normal" when watching videos)
With these settings I can watch any YouTube video or Hulu video with pretty decent frame rate, even in Full Screen!
Hope this helps. I will try to post again once my 2GB ram upgrade comes in.
