AMD GPU-PRO 16.20.3 Beta Linux Driver Released
This second beta of the AMD GPU-PRO beta driver comes with support for the Dota 2 Vulkan renderer expected to be released next week, now officially supports Ubuntu 16.04 LTS rather than Ubuntu 14.04, and contains various other enhancements. This release doesn't yet make use of GCN 1.0 support with its AMDGPU kernel DKMS driver but only GCN 1.1 and GCN 1.2 hardware. OpenGL 4.5 and OpenCL 1.2 are supported along side Vulkan 1.0.
