With the new wallet 0.3.3 I get a lot of gpu throttling down due to the "Waiting for work from pool 0".
I did not notice that before.
And same as everyone else who has replied still get HW errors on any other cards that I try and mine. Even tried putting the wallet on another computer and solo into that with a different port and no go.
dev said something about this wallet not generating "dummy work" like bitcoin does. I think if there are no new transactions to put in a block, the whole network goes idle. Right now he seems to be generating a 0.0011 transfer every 1 minute and blocks are getting resolved in around 30 seconds, so miners go idle for the rest of the minute.
I guess setting a cron job sending a small transaction back and forth between 2 wallets will keep miners busy.
