First, I'm running Vista Ultimate x64 for those curious...IDK if this will work on other OS'. Anyway, first thing I did was set up the GPU2 client like normal with all the latest drivers etc. but I went into the Advanced tab in Configuration and checked the box for Core Priority: Slightly Higher. After that, I followed the guide I put up over here for SMP folding in VMware. That's it. Really. I think the key is having the priority of the GPU2 client slightly higher than the VMware SMP client...
Pretty boring post I know but hopefully it's a useful one and will help boost our ppd as much as possible. Also, if you try it let us know how it goes and if it works (be sure to include what OS you're running).
On a side, Matt's VMware guide will probably work just as well except I could never get it to work in Vista x64 (known bug actually, nothing to do with the guide). VMplayer works fine though and IMO the installation is a bit easier.
