Loading screens and in-game frame rate limits have been redesigned to avoid unnecessary CPU spins.

Added loading times reported to LongLoadingTimesFix.log.
Changed default fPostloadingMenuSpeed value from 1.0 to 5.0.

Extract the archive into the game folder using any mod manager or manually.
compatibility
When using ENB, disable ForceVSync and EnableFPSLimit in the enblocal.ini file.
In the graphics card control panel, set the "Vertical Sync" option to "Application-driven".
Manage the "Enable VSync" setting and FPS limit in the mod's settings.
The HighFPSPhysicsFix_custom.ini file is used for compatibility with high FPS physics fix mods.
Install & use Install: follow the bundled instructions
- Unzip the archive from playbuff and read the bundled readme / instructions first.
- There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
- Place the files exactly as the readme says; mods with listed dependencies need those installed too.
- Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.
Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
