AMD’s Radeon R9 Series Graphics Cards delivers more than 3x the bandwidth per watt over GDDR5 along with a 4096-bit memory interface for incredible new advances in power and efficiency. Optimized performance for next-gen APIs including Vulkan and is designed from the ground up to give you everything you need to enjoy the latest games. OpenGL 4.5 support is coming.
CryEngine, the game engine developed by Crytek that is used by a number of large games including Crysis, Homefront: The Revolution, Ryse, and Star Citizen, now officially supports Linux. As a rather pleasing side effect of Linux support, CryEngine now also has a full-featured OpenGL rendering implementation.
