AMD Radeon RX 480 Compatibility Mode

AMD Radeon RX 480 Compatibility Mode

These drives improve the Radeon RX 480 video cards power distribution by lowering the current drawn from the PCIe bus.  There is also a new UI toggle under the Global Settings in the Radeon Software app that allow you to reduce the total power of the card, but it comes off by default. The full highlights can be read below.

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.

Fixed Issues

  • Radeon RX 480 limited PCI-E Bandwidth (PCI-E bandwidth is now at the correct speed on the Radeon RX 480) with Radeon Software Crimson Edition 16.7.1.
  • Minor stuttering no longer occurs in Grand Theft Auto V on Radeon RX 480 with Radeon Software Crimson Edition 16.7.1.
  • Video corruption will not be observed in DOOM with resolutions above 1920×1080 with Radeon Software Crimson Edition 16.7.1.
  • Hitman graphical corruption no longer occurs when the game is set to use DirectX 12 API and using zoom with weapons with Radeon Software Crimson Edition 16.7.1.

  • Battlefield 4 may experience crashes when using Mantle. As a work around users are suggested to switch to DirectX 11.
  • Need for Speed may experience flickering on some light sources in AMD Crossfire mode.
  • Frame Rate Target Control gaming profiles may fail to enable for some games.
  • Radeon Wattman may retain settings of an overclock after it has failed. If you have failed an overclock with a system hang or reboot make sure to use the “Reset” option in the Radeon WattMan settings page when the system has rebooted.
  • Low frame rate or stutter may be experienced Wolfenstein: The Old Blood on Radeon RX 480.
  • Assassin’s Creed Syndicate may experience a game crash or hang when in game settings are set to high or greater.
