Great post. Kudos to the optimization team. Hope the main menu presentation and performance are polished before release. Would be great if loading ran on a separate thread to prevent menu freezes. Also, basic actions like opening the console or pressing the "Cancel" button are still problematic.
Can you reintroduction the REAL jigglebone in ModelDoc? Just like it in gmod, it can be flexible or rigid; it's nolonger just a simple physics collision.
