To optimize power management, consider setting your system’s power profile to “Performance” mode or disabling any power-saving features that could throttle your GPU. This can be done through your distribution’s power management settings or by using tools like tlp or powertop.
Leverage Dedicated Graphics Acceleration
If your system has both an integrated GPU (e.g., Intel HD Graphics) and a dedicated discrete GPU (e.g., NVIDIA GeForce, AMD Radeon), make sure to configure your system to use the dedicated GPU for gaming. This can typically be done through your distribution’s display settings or by using tools like prime-run or optirun.
Optimize Graphics API Support
Modern games often support multiple graphics APIs, such as Vulkan, OpenGL, and DirectX (via Wine/Proton). Ensure that your Linux system is optimized for the specific graphics API used by the game you’re playing.
For example, if a game supports Vulkan, make sure you have the necessary Vulkan libraries and drivers installed. You can also try using game-specific performance tuning tools or configuration files to further optimize the graphics API settings.
Utilize Game-Specific Optimizations
Many popular Linux games and game engines have community-driven optimization guides and configuration files available. Refer to these resources to learn about game-specific tweaks, launch options, and settings that can improve performance on your Linux system.
Additionally, consider using tools like Lutris or Proton (for Steam games) to manage your game installations and automatically apply performance-enhancing configurations.
