multithreading?

    I saw somebody discussed multithreading
    But result was "later"
    But my SystemExplorer shows 3 threads
    And the most interesting is that my DelphiDebugger shows 2 threads

    Well my system says TPT is running on both of my cores, but its not. It has the same speed/ FPS as it does with one core being used. I would like multi-threading, but I don't think it is implemented yet. According to an earlier thread, there was once an attempt on multi-threading, but it was never used in the official.
    As a process, TPT is set to run on both of my cores, yet it only ever shows that it is using 50% of the processor, never any more. I only get 40-50 FPS on a blank page.

    TPT has no multithreading support. For instance, I have a quad core processor. It uses exactly 25% of my total processor (on a laggy sim - 1 core). It shows slightly higher than 25% because system processes are included.


    It is not to likely multithreading support will happen soon, as it can easily break saves - not to mention the fact that it would be very hard to code.

    There was primative multi-threading in older versions, however it was never enabled. I get this info. from a previous thread on multi-threading.

    there is some new multi-threading that helps with the new gravity that was added, it's not used in a way that would make it run faster, just to prevent gravity from making it slower.

    ok. do you think there will ever be plans for multithreading (for the purpose of spead/ performance in general) in the future?
