ATI Displays Control panel.

[samsc]

The ATI displays Control panel seems to need to be installed on recent OS builds to get the best performance out of Catalyst and Pixelmad

Users of these applications running their displays at 60 HZ might have noticed some performance problems.
And at 75HZ users might have noticed some frame tearing.

These issues seem to go away if the ATI display control panel is installed, and set to run in the configuration shown here.

Thank you Richard. This is very useful information.

Hope all is well, I'm currently a Kiwi.

Best,

Yes. Seemed to start seeming a few playback problems ( different ones ) after 10.3.5
ATI seems to have changed something.

I heard you were in NZ.

Are you crossing the Tasman at any point?

Depending on what graphics card you are using, and the state of your os, you might also have to download and install the latest graphics drivers and/or firmware from ati

if you dont have a recent mac os - 10.3.6 or later- possibly.
