it would be great if someone added a pre-compiled version for windows containing the opencl files and bin files for all the latest amd cards
p.s. i tried in so many ways to run my r9 290 (non x) on windows 8.1 following what i read here but for starters i'm a noob and the best result i got so far was seeing the hashrate go to 4.2mh/s but i wasn't getting any work from the pools and i was seeing HW errors, so i decided to roll back to my older drivers and wait for a revised or easier to run version for windows.
This version was designed with 14.6 driver in mind. If you are using win 8.1 then you have no excuse to stay with the old amd drivers
the working windows binaries are on the OP.
