2. Purchases Path
   Sets the path where newly purchased assets will be stored as a default location.
3. Undo Actions / History Limit
   Sets the number of undo levels. Higher numbers will give you a larger and more flexible undo history but at the expense of increasing RAM usage.
4. Max Scene Backups
   Sets the number of scene backups. Higher numbers gives you more security but uses more hard drive space.
5. Max CPU Threads for Simulator
   Configures the number of CPU threads dedicated to calculating the simulation. In most cases the default Auto setting provides optimum results but you can disable this and define the number of threads manually.
6. Max Baking Ram Buffer Size
   Configures the amount of RAM that can be used for baking animations before saving them to disk. In most cases the default Auto setting provides optimum results but you can disable this and define the amount of RAM manually.
7. Display System Units
   Sets the display units to either Metric (cm, m, km) or Imperial (in, ft, mi). Its important to make sure your system units are the same in Anima as they are in your final rendering application.
8. Render System
   Configures graphic display drivers on the viewport. You can choose from OpenGL or direct3D.
9. Enable System Data Modification
   Allows you to enable or disable the modification of system wide data. Use with caution as changes to the system data set will affect all projects.
