muddocktor said Just set up another folder named differently from the first instance(I name my folders folding1, folding2, etc) and set up another instance of the console client. When you configure this new instance, set everything up the same way as your first instance except give it ID #2, since the first instance should be ID #1. Then go ahead and make a shortcut to start it like you would the first instance and use the flags that you normally use on the first instance. Then go ahead and start the second instance up and presto, you will have both procs folding. Since the client is not smp aware, you have to have 2 instances running at the same time to utilize both processors. That's why with only 1 instance running, you only see 50% utilization because the other proc is doing nothing except burn electricity.
