AMD has tweeted that it is working on drivers that should fix the micro-stutter problems experienced on systems with multi-GPU setups.
AMD announced through its Radeon Twitter feed that it is working on better drivers that will improve CrossFire performance, with particular attention to frame latency issues. AMD calls this frame pacing. Supposedly, the driver will be available on or around July 31, 2013.
While this driver release might not be that exciting to single-GPU users, it is something over which users with multi-GPU setups should get passionately excited. The reason for this is that over the last couple of years, problems with frame latency in AMD Radeon CrossFire systems have gotten increasingly apparent and have been quite bothersome.
The problem in question doesn't have a scientific name, though the term "Micro-Stutter" is widely accepted. The problem is that while a multi-GPU system may pump out, say 40 FPS in a particular game, the frames do not come out with consistent timing between each other, thus appearing as if a much lower frame rate is being produced. Many benchmarking procedures now include frame latency testing, sometimes putting as much, if not more, emphasis on the topic of frame latency as actual FPS performance.
