MSFS: Shader Cache Cleaners

The shader cache cleaner (aka the disk clean-up tool) can remove a lot of stutter clutter by deleting files that are no longer in use. Here is a good description you can follow that include the glcache folder. Once you are done, MSFS will take some time to rebuild is shaders as necessary and will then settle down.

When to Clear the Files

A good time to delete these files is:

• after a driver update
• after a sim update
