I love the miner its better than any miner for monero for r9 270x cards. I've tried every setting possible for weeks to get xmr-stak to run good for me and it won't ever get more than 360 h/s but claymore will push 420 h/s sometimes higher. Not to mention xmr-stak lags my computer out so bad that I can't even use its completely unusable. I have to stop the miner in order to even type this message otherwise it would take me about 30 seconds to even try to fill this message out. I've been trying settings for weeks and nothing gets better than 360 and nothing stops the lag. Claymore runs so smooth its crazy I can do anything I want without any lag at all and running 400+ h/s. Even if he takes two more months to do an updates its worth it.
