A tool which reorganizes a project directory that speeds up project's compile time up to 70%.
MCTO moves 3rd-party script files into Unity special folders to minimize the risk of breaking anything. After it’s done, they won't be recompiled on each compiler run. Mad Compile Time Optimizer handles every project with caution. If any operation fails, it triggers the revert immediately.
Working on all Unity versions
Keeping track of your optimized files
Reverting if anything goes wrong
Changing stored in files (can be used with SCM)
The actual speed gain depends on your project setup.
