Anandtech have thrown up their 64bit Windows XP Driver Comparison!
Recently, ATI released a beta version of their 64bit Catalyst drivers, and we have spent the last week playing around with various hardware and games on this new platform. There is some good, and there is some bad (as is always the case), but it is definitely a good thing that ATI has joined NVIDIA in the 64bit public beta department. The more testing that can get done on these drivers before their release, the smoother the transition should be when final versions of everything become available. What we eventually expect to see when running 32bit games under a 64bit OS is a slight improvement in performance, but nothing to write home about. The main reason for this is the availability of extra resources to the operating system and drivers running on the system. The increased availability of registers and other enhancements of x86-64 will provide the operating system with a slightly more efficient means of managing processes and resources. Drivers will also have this added benefit when bridging the gap between software and hardware. The 32bit software is still limited by what it percieves as the limitations of the haredware, so it won't be able to really take hold of the possibilities for performance improvement.
