FPS Stabilizer

This mod increases the FPS by overriding the default "worst allowed FPS" from 22 FPS to Unity's target frame rate. It achieves this by reducing the number of ticks processed per frame, resulting in a more stable and higher FPS, and almost unchanged TPS.

The changes of the mod take effect only if load is high and cpu cannot handle it. In this conditions vanilla allows FPS to be 22 at best, this FPS drop frees time to do more TPS. This mod allows FPS to be 60 at best, so there will be less freed time.
There is a deal: buy extra FPS for time, that vanilla assigned for TPS during FPS drop.
Installing this mod, you buy as much FPS for this price as possible without allowing cpu to just wait.

The mod may not work only if something changed the 'TickManagerUpdate' function. It can be just some other optimization mod. Rocket Man, Performance Optimizer and Performance Fish are surely compatible with FPS Stabilizer.

Thanks to Cosmic Lustyness for the TPS&FPS mod, which helped to make preview.
