Hi all,
RadeonPRO lets you do some really nice things with your ATI card. SMAA is really fast for source games, and FXAA looks really nice for alpha masked foliage.
In the Tweek section you can set the Vsync to Dynamic which removes almost all V-sync mouse lag.

There is a way to use SweetFX with Radeon pro too. This adds some really nice post processing effects like Sharpen, and Vibrancy.

Just unzip it somewhere on your Hard drive, and look in the RadeonPro's setup to specify where the SweetFX folder is.
I just use the Sharpen and Vibrance for SweetFX, and it really looks nice
