Post any bugs you find here. But there aren't as many bugs that are really bugs and I don't already know about than when this first started, so also use this as a general conversation save, or to ask / tell me anything. #1 most commented save in tpt!

    This is LISP: ((((())(((())))(()())((())))(()((()))(()))()((()))())()((())(((()()))())()))

    Just found out that the controller on a lego model of a spider I made back in 2014 runs on LISP. I'm still having a great deal of trouble programming it as there is no usable port on it. Also the language itself is pretty hard its not user friendly...

    @jacob1 Ok, thank you. (You are also my favorite moderator.)

    Also PortalPlayer, I have no idea why SDL2 is slightly slower, but I think it's because the software renderer was quick since we already had the entire render ready to give to sdl. in sdl2, I have it going through the accelerated renderer (gpu). I tried this morning to have an option to only use the software renderer, but couldn't get it to work.

    it's mostly single threaded, but there's a few things in other threads like newtonian gravity, and save / thumbnail downloading in the save browser.

    I just had a question, is TPT more single threaded or multi-threaded?

    jacob1: Right, that makes much more sense :) So now I'm wondering why SDL2 would make single scale slower.

    double scale mode is for sure slower. But, in SDL2 double scale mode is now much faster than it used to be. And single scale mode is slower than it used to be. They are very close in speed in SDL2, they are pretty far apart in SDL 1.2

    PortalPlayer: My computer has 3.4GHZ CPU and it used to run TPT at 500FPS. Now it runs it at 160FPS max.

    Now I'm confused. Is double scale supposed to perform better or worse than single? "In double scale mode or higher, it's a lot faster." "it has to draw everything 4 times, making it over 4x slower."
