Catalyst A.I setting in CCC

[SkeeterUK]

What exactly does it do? At the mo its set on standard so im woundering what disabled/standard and advanced does for each.

All I know is that it needs to be on standard or advanced for HDR+AA, that's about it.

I think it dynamically controls texture/filtering levels.

Catalyst A.I: Catalyst A.I. allows users to determine the level of 'optimizations' they enable in graphics applications. These optimizations are graphics 'short cuts' which the Catalyst A.I. calculates to attempt to improve the performance of 3D games without any noticeable reduction in image quality. In the past there has been a great deal of controversy about 'hidden optimizations', where both Nvidia and ATI were accused of cutting corners, reducing image quality in subtle ways by reducing image precision for example, simply to get higher scores in synthetic benchmarks like 3DMark. In response to this, both ATI and Nvidia have made the process transparent to a great extent. You can select whether you want to enable or disable Catalyst A.I. for a further potential performance boost in return for possibly a slight reduction in image quality in some cases. You can choose the aggressiveness of such optimizations, either Standard or Advanced on the slider. The Advanced setting ensures maximum performance, and usually results in no problems or noticeable image quality reduction, so it is recommended you enable Catalyst AI and set it to Advanced. If on the other hand you want to always ensure the highest image quality at all costs, disable Catalyst A.I. (tick the 'Disable Catalyst A.I.' box). I recommend leaving Catalyst A.I enabled unless you experience problems, as many application-specific optimizations for recent games such as Oblivion are dependant on Catalyst AI being enabled.

Hmm so.. Standard or advanced, what would you use?

That article made me chuckle, because I always got higher 3D Mark scores with Catalyst A.I. set to off.

I use neither, i have it disabled.
