I haven't had any issues with Posing and P6, if anything I find it easier to manipulate the higher res figures using the openGl interface. I'm wondering if some of this is card related? I'm using an Nvidia ti-4200 with the latest drivers. You could make sure your drivers are up to date, especially if using the openGl preview mode in the Pose room. It sounds more to me like you have a bottleneck somewhere, whether older drivers or a TSR running in the background. I also tend to deactivate most of XP's slowness culprits like the Indexing service and system restore (of course, you're on your own if you want to try those things ;) ) I'm also using the P6 Sr-1 and I find the libraries more responsive but some have seen the opposite, especially due to lots of nested runtimes but this is documented in the SR-1 readme as well. As far as possible P4-specific features causing a problem, I'm not sure. You could try deleting the associated .obj geometry .rsr but as far as I know, ProPack and upward ignore them anyways.
