Methodologies

Getting Shader Cache and Compat Data

• Native Python file methods are used to get all of the subdirectories in the home/deck/.steam/steam/steamapps/shadercache and home/deck/.steam/steam/steamapps/compatdata parent directories
• Each subdirectory name is a steam appid/gameid

Getting Steam and Non-Steam App Names/Types

• Since each game directory name is an appid/gameid, it can be used to fetch the game name via the client side Steam appStore.GetAppOverviewByGameID(game.appid) method. This method returns an object with a display_name property, which is the name of the corresponding steam or non-steam game

• appStore.GetAppOverviewByGameID(game.appid) also returns the app_type property, which is used to differentiate between Steam and Non-Steam games

Clearing Shader Cache and Compat Data

• Game specific shader cache is deleted recursively by appid (directory name) using the shutil.rmtree('home/deck/.steam/steam/steamapps/shadercache/<appId>') native Python method

  Shader Cache will regerenerate either during gameplay or preemptively via OTA (over the air) updates via Steam

Detecting Games That Don't Support or Have Never Synced to Steam Cloud Saves

• appStore.GetAppOverviewByGameID(game.appid) returns the local_per_client_data.cloud_status object/property, which is used to check if an installed game is/has ever synced to Steam Cloud Saves
