Download the ImDisk Toolkit (open source) and install:
https://sourceforge.net/projects/imdisk-toolkit/



Set 1024 MB, Allowcate Memory Dynamically (optional), Drive Letter pick what you like (I chose R: for RAMDisk), Set TEMP Variables

If you have more RAM to spare (>= 32GB) I recommend 2048 MB and Allowcate Memory Dynamically



Click Set All To R:



Confirm twice with OK - the tool creates a virtual drive which hosts your TEMP files, making your PC now faster whenever an app access the TEMP folder. After the app said it has mounted the drive, you can exit. In your Explorer when accessing your Computer overview there is now the new R: drive. Of course here you can also set the app for LevelCache instead, or use both by utilising additional softlinks (junctions).

Here is a guide on how to setup softlinks
