I'll add a 'yes' to that, as well. At the moment, you get the best performance from having both P4 and P5 installed (better even with PP, as then you can output to other high end packages through the plugins...and you need a valid P4.exe to export to Vue d'Esprit if you use that. You can't do any of the P5 dynamics or shaders yet, but E-on is working to get Vue to talk to P5). The current CL team is working on and SR-3, and considering how quiet they have been on it, either it is smoke, or they have the bit in their teeth and are killing as many of the bugs as they can before releasing.
