Hello, my hashing rate has been decreasing over the past few days. Using a GTX460 in solo mode with RPC Miner, I was getting 52.8 Mhash/sec two days ago, and today I'm getting 50 Mhash/sec. I may have even been getting 56-58 Mhash/sec five days ago, but I'm not too sure.
Was there an increase in difficulty? Would that drop my hash rate? Or has something changed with my configuration (though I'm pretty sure nothing has)?
And I'd sure like to try poclbm, but it can't establish RPC communication with my Bitcoin client, only doing hashes for 5 seconds erratically every 2 minutes.
