thanks for sweeping the topic under the carpet ( sorry, moved to linux support here : )

But it is not only Linux issue, with Windows it is the same problem.

With 12.10 drivers it works (I have to disable optimizations - probable cause is AMD_BFI_INT) well,

with 13.8beta it returns incorrect GPU sum compared to CPU.

Full log is here:

You can try yourself ::

Windows + 13.x drivers + 7xxx card ?
oclvanitygen -v -i -d9 1Lostx
###select proper GPU
oclvanitygen -v -i -d0 1Lostx
###wait 15 seconds

As stated before "Please help me improve the long time bad driver reputation AMD always had." but I do not believe it much now, I am going short with AMD again

You'd have more luck posting stuff like this in the developer forum. It has hardly anything to do with gaming. Probably that's why your previous thread was ignored.
