So anyone with a dual GPU solution in their PC is likely aware of the discussion around micro stutter. Recently Nvidia made it's internal testing method for this issue available to the press to usage in evaluating dual card/gpu setups. As a result people were finally able to see some hard evidence for the following.
- The effectiveness of Nvidia hardware and software based frame metering technology in managing microstutter
- How AMD's lack if frame metering can really damage the end result of what is a fairly costly investment
Up until now the only evidence for Crossfire's seemingly larger problems with microstutter has been purely anecdotal which understandably meant that many people took it with a grain of salt. However this new FCAT tool really demonstrates that AMD has had a serious problem in the multi-GPU space for some time now. Fortunately as soon as the numbers were laid out in front of them they set to work on some new software level frame metering to try and resolve the issues.
The video bellow (length/tech talk warning) put out by PC Perspective goes through how the new tool works and the results of their original tests. Additionally they discuss the changes that AMD is making with a new prototype driver to address the enormous difference between the two manufacturers.
Personally I'm pretty keen to get my hands on the new AMD driver once it's reached it's final state and pull my old 5870's out of the cupboard for a test run. I retired those things much earlier than intended due to the significant problems I had trying to get a smooth game play experience at high resolutions.
