AMD released version 16.5.1 of its Radeon Software Crimson Edition drivers yesterday. As one might guess by the version number, this is the first release this month, and AMD describes it as a hotfix release. The sole remark in the patch notes regards Microsoft's new free-to-play racing sim Forza Motorsport 6: Apex. The company promises up to 27% better performance in that title on the flagship R9 Fury X versus its last driver release.
That sort of performance boost sounds important, since developer Turn 10 recommends a Fury X (or a GeForce GTX 980 Ti) to achieve 60 FPS at 4K. Even at 1080p, the system requirements suggest a Radeon R9 290X (or a GTX 970) to achieve that 60-FPS number. It seems some bug fixes may have made their way into the new driver, too, as the list of known issues has been trimmed slightly since the last release. The drivers are available now from AMD's download page.
