Catalyst Perfomance

[samsc]

I've never got more than 4 layers of AIC at 1080p 25fps on ANY MacPro... not even the same spec as you quoted.
How do you manage to get 6-8 layers on 2009/2010 MacPros?

suggest you run test G on your systems and send charts.

and we can check the spec of the machines you have-
