BL4 Optimizer

Please Endorse if this mod has helped!

UPDATE: Now Supported By SteamDeck & Handhelds!

The BL4 Optimizer is a simple, yet powerful, application designed to streamline the process of optimizing your game settings in Borderlands 4. Instead of manually editing the GameUserSettings.ini

file, this tool provides an easy-to-use graphical interface to manage your performance and visual quality.

The key to the BL4 Optimizer isn't just changing the in-game options, it's about tweaking dozens of hidden engine console variables that a user can't access from the menu or even see in the default GameUserSettings.ini file.

Here are some of the advanced performance tweaks BL4 Optimizer makes:

• []Shader Optimization: It enables shader caching and removal of unused interpolators, which can significantly improve rendering efficiency and reduce stuttering.

  []DirectX 12/GPU Optimization: It adjusts settings like D3D12. Bindless. ResourceDescriptorHeapSize and r. UseFastIntersect

  , which directly optimize how the game interacts with your GPU's hardware.[]Parallel Processing: The optimizer forces the game to use your CPU and GPU more efficiently by enabling parallel processing for rendering, shadows, and physics scenes.

  []Performance Metrics & Debugging: It disables numerous debugging and logging features, such as r. GPUCrashDebugging, that are active by default but can consume performance.

  []Streaming & Memory Management: It adjusts settings to optimize how the game streams textures and manages memory, which can improve loading times and reduce hitches.

  []Input & Mouse: It disables mouse smoothing and view acceleration, ensuring more responsive and accurate aiming.

  []And dozens more...

  Key Features

  • []Optimization Profiles: The tool comes with pre-configured profiles tailored for different PC builds. Choose between:

    []Performance (Max FPS): This profile sets graphics to the lowest possible values to ensure the highest frame rate. It is ideal for players who prioritize performance above all else.

    []Handheld/SteamDeck: This profile is specifically tuned for APU systems like the Steam Deck, ROG Ally, and other Windows handhelds. It balances high visual fidelity with strict power and thermal constraints (TDP), prioritizing stable performance and battery life.

    []Balanced (Quality & Speed): This profile offers a balance of visual quality and performance by setting key graphics settings to medium.

    []Recommended (Optimized): This profile offers a balanced blend of visual quality and performance. It intelligently adjusts key settings, like shadow and global illumination quality, for a significant FPS boost without a major visual downgrade.

    []Ultra (Maximum Visuals): This profile sets all graphics settings to the highest possible values for the best visual experience.

    []Intelligent Settings: The optimizer automatically detects your GPU's VRAM, CPU, and RAM to apply the correct texture quality settings. This ensures that you get the best possible visuals without causing blurry textures or stuttering on lower-end hardware.

    []Lumen Toggle: A new toggle button has been added that provides complete control over Lumen, a key feature in Unreal Engine 5 that provides dynamic and global illumination. When enabled, it applies the Lumen quality setting for the selected profile. When disabled, it sets the Global Illumination Quality to 0, turning it off for a significant FPS boost.

    []Fog Toggle: A new toggle button has been added that provides complete control over Fog and Volumetric Fog settings. Volumetric fog, while visually impactful, is a significant performance cost in Unreal Engine 5. When enabled, the toggle applies the fog and volumetric fog quality setting for the selected profile. When disabled, it sets the related console variables to zero, turning both off for a significant FPS boost.

    []Backup & Restore: Never worry about losing your custom settings. The tool allows you to create backups of your current GameUserSettings.ini file, and restore them at any time. You can also import and export profiles to share them with other players.

    []Restore to Defaults: The application includes a "Restore Defaults" function that safely deletes your GameUserSettings.ini

    file. The game will then automatically create a fresh version with its original default settings the next time you launch it.[*]User-Friendly Interface: With a clean and straightforward design, the BL4 Optimize
