Multi threaded simulation

Description
ATTENTION
  1. In summary, ONI uses two threads. One is main program, for duplicants / critters / plants / buildings / etc, another is for simulation like heat transfer, fluid movement. This mod enable multi threads for simulation.

  2. This mod is written by C# and C++. If your game crashes while loading, please install newest Visual C++ Redistributable Package[learn.microsoft.com]. You can also find a copy in the mod folder.

  3. To support multi threads and avoid threads conflict, it is necassary to reconstruct the algorithm of original game. Therefore the simulation result might be different with original game.

  4. Your game fps may not increase with this mod. In most cases, the performance bottleneck is main program.

  5. If the core number of your CPU is less than 4, it is a bad idea to try this mod.

  6. This mod ONLY supports windows OS.

  7. Except 7/8/13, the others 12 features listed in this post[forums.kleientertainment.com] are removed from this mod.

Whoa, this is very cool.

Managed to spend some time on this, and got it working, I can confirm it indeed does utilise more cores, however, at standard speed it's ok, but if run speed is increased there are massive framerate issues, like its only displaying 1 frame out of 3

@NAREBOX I was try it nearly one week ago but it's didn't work like you. But today somehow it work after I installed AIO Runtimes

Can confirm it works on linux using proton(I used protonge).
For those looking to try it on linux you need to also install the vcredist, top comment here explains how. Reddit Link

To continue onto my previous comment, it unfortunately runs identically performance wise, however, its still great to have in case at one point the simulation spikes for some reason.
Although native version runs better for me, would like to use this there too, linux does have "libSimDLL.so", the .so being the linux dll equivalent.

@NAREBOX
It seems that you have encountered the same problem as @MiserableGamer
Sorry that I can't give you any effective advice.

Hello @R9MX4 First of all, thank you very much for creating this amazing mod. Unfortunately, it didn’t work. I have all versions of the C++ packages updated, my Windows 11 is on the latest 24H2 build, and I’m using a Ryzen 7 5700X3D. When I try to load the save with your mod enabled along with the others, a Unity window opens, then closes along with the game without showing any warning. https://imgur.com/a/DBP0KK1

When the mod was activated, the game worked fine, but the next day, when loading a save, the game started to crash. At first I thought it was a conflict with Piped Everything, but then I disabled Fast Track and the save loaded normally.

Huge thanks to R9MX4 for the Multi Threaded Simulation mod! 🙏 My ONI performance skyrocketed, finally all 20 cores of my Intel Core Ultra 7 265KF are being put to good use. After the upgrade, the game used to struggle as soon as my colony got a bit complex, but now it runs beautifully. Really appreciate your work!

My suggestion is manually uninstall Redistributable Package, reboot, then install the new one.
If the strategy not work, maybe you can try to download the visual studio 2022 and install the c/c++ module.

I am sorry I can't give more effective suggestion.
