always86 is correct (and as you say, is also doing a great job). The render queue is made up of statics that have been posed but are waiting for processor time to render. All completed statics have also been posed, but not all posed statics have been rendered when there's a (non-zero) queue. DPC currently has ~3073 renders
completed, which is the usual metric we track.
In theory it's also the most important metric since statics will only be added to the game once they're complete. But I'm sure DPC's animation rigs could chew through the static queue in no time if the animations were finished. So in this case the difference between posed and complete statics is moot compared to the number of complete animations - which is currently unknown.
