 ## Compatibility
 
-As of October 2022, Ryujinx has been tested on approximately 3,600 titles; over 3,500 boot past menus and into gameplay, with roughly 3,000 of those being considered playable. You can check out the compatibility list [here](https://github.com/Ryujinx/Ryujinx-Games-List/issues).  
-Anyone is free to submit a new game test or update an existing game test entry; simply follow the new issue template and testing guidelines, or post as a reply to the applicable game issue. Use the search function to see if a game has been tested already!

There are currently four graphics enhancements available to the end user in Ryujinx: disk shader caching, resolution scaling, aspect ratio adjustment and anisotropic filtering. These enhancements can be adjusted or toggled as desired in the GUI.
