Short description of error
When rendering cube in 2.76b with Hawaii(Firepro w8100) my render time is 2.19 seconds. When rendering a cube in 2.77a however the render time jumps to 23.11 seconds. Can't render bmw render test or anything intensive as it feels like it has crashed it takes so long.
Uinstalled the GPU drivers of both cards and installed previous driver for Firepro but still has issue. My Fury X has gotten a lot faster in 2.77a, being that a cube render went from 3.25 seconds in 2.76b to 1.2 seconds in 2.77a. So I'm not sure why the Firepro got that much slower.
