Symbol annotated profiling report from OProfile

When running World of Warcraft: Legion (Version 7.2.0.24015) using the D3D11
renderer, framerates are severly limited by the time taken in
shader_arb_select.

I am using a GTX970 with the proprietary NVidia drivers.

Below I have attached the symbol annotated samples produces by oprofile, along
with annotated source of arb_program_shader.c showing that fragment shader
binding seems to be the core issue.

Please do not hesistate to ask for any other information, I'll gladly help out.
