AMD has released Radeon Software Crimson Edition 16.7.1 for Windows

Radeon Software Crimson Edition is AMD's revolutionary new graphics software that delivers redesigned functionality, supercharged graphics performance, remarkable new features, and innovation that redefines the overall user experience. Every Radeon Software release strives to deliver new features, better performance and stability improvements.

Radeon Software Crimson Edition 16.7.1 Highlights
The Radeon RX 480’s power distribution has been improved for AMD reference boards, lowering the current drawn from the PCIe bus.
A new “compatibility mode” UI toggle has been made available in the Global Settings menu of Radeon Settings. This option is designed to reduce total power with minimal performance impact if end users experience any further issues. This toggle is “off” by default.
Performance improvements for the Polaris architecture that yield performance uplifts in popular game titles of up to 3% [1]. These optimizations are designed to improve the performance of the Radeon RX 480, and should substantially offset the performance impact for users who choose to activate the "compatibility" toggle.
