Introduction

As the month of public holiday's rolls around for Australia, we have a new set of ATI Catalyst drivers to test just before we take a nice long weekend off. As expected the 6.4 are their name and performance and bug fixes are what they bring to the table.

Let's have a quick look at the release notes before we get stuck into benchmarking.
