[Bf-committers] I can't use Opensubdiv on 2.79 RC1 with an AMD RX 480 (Linux)

[Sergey Sharybin]

Blender requires decent OpenGL for drawing OpenSubdiv meshes. This is the
only way to get decent speedups.

But it's not all that sad as it sounds! In Blender 2.8 we've switched to
OpenGL core profile, which has higher OpenGL support than the compatibility
profile we use in 2.78/2.79. Unfortunately, we did not hook up OpenSubdiv
in 2.8 branch yet.

So with 2.8 OpenSubdiv support will come to more hardware (including Apple
macOS) with more features (like adaptive subdivisions).
