Balatro: Best config.json for Card Effect Performance

The primary goal for Balatro optimization is Logic-to-Animation Synchronization. As your “Joker” synergy grows, the game must process dozens of triggers per hand. This configuration focuses on increasing the “Game Speed” beyond the menu limits and disabling the more demanding visual filters like “CRT Bloom” and “Pixel Smoothing” that can cause micro-stutters on integrated graphics or handhelds like the Steam Deck.

Hardware Compatibility & Expectations

• The LÖVE Engine: Balatro is exceptionally well-optimized, but its “CRT Shader” is a post-processing layer that can be demanding at 4K resolution.
• Handheld Efficiency: For Steam Deck or Rog Ally users, lowering the “Shadow” and “Bloom” settings via the config can save up to 2-3 watts of power, extending battery life during long runs.
• Refresh Rate: Balatro feels best at 60 FPS; however, setting your monitor to 120Hz/144Hz can make the card-selection “snap” feel significantly more responsive.

File Location

Balatro stores its configuration and save data in the AppData directory. The file is a standard JSON format:

%APPDATA%\Balatro\settings.json

Technical Configuration (Code Block)

Open the settings.json file with a text editor. Modify the following parameters to prioritize performance and animation speed:

{
  "allow_vibration": false,
  "crt": 0,                     // Set to 0 to disable the heavy CRT shader
  "fps_cap": 144,               // Set to match your monitor's refresh rate
  "game_speed": 4,              // 4 is the max in-game; higher can be forced via mods
  "graphics_quality": 1,        // 0 = Low, 1 = High
  "master_volume": 60,
  "mouse_confinement": true,    // Prevents accidental window-outs during fast play
  "pixel_perfect": true,        // Ensures sprites align with the pixel grid
  "shadows": "off",             // Disables card drop shadows for better FPS
  "vsync": false                // Recommended OFF for the lowest input latency
}

Strategy for Card Effect Performance

To ensure your “Scientific Notation” scores don’t crash the engine:

• The CRT Shader Trade-off: The “CRT” setting (crt: 0) is the biggest performance gain. The scanline and curvature effects are nostalgic but require constant pixel-shading math. Turning this off creates a much cleaner, sharper 2D look.
• Game Speed Maxing: Always play on 4x speed. Balatro’s “Fast Mode” is found in the in-game settings, but ensuring it is hard-coded in the JSON prevents the engine from defaulting back to 1x after an update.
• Shadows and Bloom: Setting shadows to “off” removes the dynamic drop-shadows beneath the cards in your hand. This reduces the number of draw calls per frame, which is vital when you have 10+ cards in hand due to “Spectral” buffs.

Key Performance Parameters

Parameter	Recommended Value	Impact
game_speed	4	Reduces the duration of card-flip and trigger animations.
crt	0 (Off)	Eliminates the most GPU-intensive shader in the game.
shadows	off	Lowers the rendering overhead for the card hand UI.
pixel_perfect	true	Prevents the “shimmering” effect during card movement.

Conclusion and Expected Results

By manually refining your settings.json to prioritize high-speed animation logic and disabling non-essential post-processing shaders, you are creating the ultimate environment for “Endless Mode” grinding. You can expect instantaneous trigger resolutions, longer battery life on mobile devices, and a crystal-clear visual style that lets you focus on your deck’s synergy.
