Okay, so, here's the thing. I'm starting out mining on a pool with my GTX 460. Of course, being a pool, there's a minimum efficiency I have to meet. I get 80% efficiency with the Phoenix miner, and 52 Mh/s average. This is okay. The thing is, with the RPC CUDA miner, I get around 62 Mh/s average, which is almost a 20% improvement. The problem is, this miner drops my efficiency to 10%, which is just awful. I know this is a very noobish question (I guess that's why this is the newbie section), but is there some sort of flag I could set to make the RPC miner more efficient? I really wouldn't like to waste that extra 20% potential from my GPU. (Also I just noticed that Phoenix is constantly using a whole core of my CPU, which RPC didn't do.)
