ince Crimson 16.10.2 you can no longer use OpenCL drivers from older driver packages.
Users using their graphics cards for rendering through OpenCL (and mining too) know that the OpenCL files packaged with version 15.12 package (which correspond to OpenCL v1915.2) were the most stable and also pushed more performance out of AMD's cards.
I tried right upto 16.8.2 and I was able to use older drivers by replacing the following files in the driver extracted files:
This no longer works after 16.10.2 and you are forced to use the newer buggier version of OpenCL. It sucks because newer games (Hitman etc) need the latest drivers to run smooth and therefore consumers are left with a difficult choice.
Im currently on 16.11.4 and like 15 mins into rendering i get the "THREAD_STUCK_IN_DEVICE_DRIVER" error and atikmdag.sys is the one causing the error.... application used is LuxRender
