Tweaks

Tweaks are various settings (like loaders and launch options) that can improve performance, compatibility or add new features. Tweaks are defined with JSON files in the tweaks/ folder in GameHub's config directory.

Included tweaks

The following bullets are tweaks that are included in GameHub:

• Feral GameMode - apply temporary optimizations to the game process and OS
• Radeon ACO Vulkan Compiler - use a hardware-based shader compiler on AMD GPUs, improves loading times with DXVK and native Vulkan games
• Wine/Proton specific tweaks - used to improve compatibility with some Windows games

Additional tweaks

The following tweaks are additional tweaks done by the community. The JSON files will be located under the tweaks/ directory. Everything between and including { and } will have to be pasted in the JSON files.
