I am a bit perplexed.
h.264 playback sutters at times on the following system
P4 820D
1GB DDR2 667
Nvidia 6600GT
I had tried overclocking the video card substantiually (20%) but no change and neither does memory (adding subtractin etc) make any difference. This leaves only the CPU yet throttlewatch shows maximum usage around 80% of both cores with no throttleing.
This is what has me perplexed. As the 6600GT has no H.264 accelleration all computation falls on the CPU leaving it as the likely culperate, yet if the cpu is to blame, why is it not maxing out. (Again no throttleing is reported)
EDIT suttering is shown as reduced frame rate in Quicktime 7 so it is not the monitor agaik.
File tested in king kong trailer avialable at www.apple.com/trailers
I will try in the next couple of days on a 3800+ and 4200+ X2 system as well as 3800+ SC but this has me genuinley stumped.
