I've had a weird issue with DSON and Poser 2012. There's some sort of strange memory issue going on during rendering, making me think that DSON is a bit too "resident" once Poser is started, taking up a bit of room or interfering with my render cache for some reason. I can not confirm this, however.

DSON would not fully uninstall, either. It left orphaned wacros that Poser attempts to call, requiring manual uninstallation. All in all, color me "not impressed."
