would have posted this here (https://bitcointalksearch.org/topic/gui-mining-updated-dec-3-with-7970-bugfix-also-supports-stratum-3878), but can't cause I'm new (in fact, I registered only because of this question I had, but maybe I'll use this forum in the future, who knows...
). But maybe a mod can move my post there?My problem is: until now I used an older GUI Miner version from 2011-05-01. Worked fine. Today I saw, there's a new one: 2012-02-19. Works also fine, but on my laptop it is significantly slower than the old one (9 instead of 13 MHash/s - that's 30% decrease in power!). All the settings stayed the same. Does anybody else have this problem?
