    Proper patch notes to come at a later time, but the major updates are as follows:

    • Local Server multi-threading across planets and AIs
    • LZ4 compression for server mods
    • AI improvements and multi-threaded
    • Client and Server improvements
    • Crash fixes and perf improvements.
    Some details put together by mikeyh here: https://wiki.palobby.com/wiki/PTE_Testing

    You've managed to multi thread the simulation?!?! I'd be fascinated if the team could give an overview of what went into that, as that has the potential to totally change the scope and scale of the game, kudos!

    For the navigation part, each planet now runs in its own thread.
    For the AI part, each AI also runs in its own thread.

    So multi planet systems are now expected to be much(!) faster than they were before, possibly even faster than single player systems.

    Only downside: When using local server, and eight-core or better CPU is now IMHO recommended.

    As explained in the Wiki, also a ton of other performance improvements, especially regarding navigation (planet wide patrol became much cheaper!), and many, many fixed crashes.

    Since nav and physics run on a per planet basis, it was a no-brainer to look into multi-threading those parts of the sim. So, each sim tick each planet gets to run its nav and physics update on its own thread (or, up to as many threads as are available, which depends on the number of cores you have).

    The copy sim history portion was another thing that just made sense to multi-thread. Since we are acting on each individual entity history there wasn't much overlap.

    Then came the AI. This was a little bit more complicated since the AIs share neural networks and they query the unit type database, which can cause data to change, but it works. Each AI gets its own thread (again, limited by CPU cores) to do it's update.

    Additionally, the history server update is also multi-threaded, since, like the copy sim history step, it is acting on individual entity histories.

    This pleases me. This pleases me greatly. I dare say I feel the tug on the proverbial leash as it were.

    They said it couldn't be done.

    'They' didn't realise this is Uber we're talking about.

    You guys are incredible.

    You're a god ;*

    Anyway, what does mean the "local" server part in patch notes? It doesn't work on Uber servers?

    Not yet I'm guessing- the Local server is the offline ability- although there is a way to host your own local server and make it available publicly anyway, @Quitch has the details...

    Well I've just tested a 6 way FFA on Pax Prime with the MT server mode on vs 5 absurd AI.

    I let the AI expand and build out all the planets for 30 mins. No slow down, still holding 30fps with 10fps sim speed at the end. That's very impressive!

    Just one issue, I had a server crash whilst loading the game on the first attempt (during planet loading in the lobby). Once in game it all went fine. Overall CPU usage was around 60% towards the end on my FX8320. I certainly think my machine could handle quite a lot more based on that. I need to try an 8 planet system next :p
