I have 2 x 7970 running on WIn7x64.
After updating from cgminer 2.0.3 to 2.1.2 I lost about 40 per GPU! (10%).
At the same time I also updated from Catalyst 11.6 to 11.12 (because of the 100% CPU load bug).
Now I want to use P2pool mining - but that only works with cgminer 2.1.2.
Is there a way to get the speed from 2.0.3 to 2.1.2? I mean, are there some compiled kernels, bins, etc. that I can simply copy from 2.0.3 to 2.1.2 ?
