What PenguinBurner is

PenguinBurner is a free, open-source Linux app for tuning NVIDIA GPUs, with automatic undervolting, overclocking and per-game settings. Its Auto-UV process runs a managed Q2RTX benchmark and CUDA workload to find and verify stable voltage-frequency curves. Adaptive mode can switch among saved Efficiency, Balanced and Performance profiles to target a game’s FPS and lower power use when there is room to do so. It needs at least two usable tiers to switch; with one tier, it keeps using that profile.

A shared game library supports Steam, Lutris and Heroic. Profiles apply when a game starts and the app restores the standing profile when it ends. The overlay can show base and frame-generation FPS, PC latency, GPU clocks, power, temperatures and the active tier. Manual voltage-frequency and fan-curve editors are included, along with an automatically generated silent fan curve. Users can import MSI Afterburner curves and export saved curves as NVIDIA LACT configurations. The install guide lists RTX 30, RTX 40 and RTX 50 series cards, and says to install the proprietary NVIDIA driver and CUDA first. Installation options include pip, Flatpak, Fedora COPR, Arch or CachyOS AUR, and Ubuntu PPA packages.

Who it suits

PenguinBurner suits Linux users with supported NVIDIA RTX 30, RTX 40 or RTX 50 cards who want automated or manual GPU tuning. It also fits players who want profiles tied to games in Steam, Lutris or Heroic.

What it does well

Auto-UV finds and verifies stable voltage-frequency settings.
Adaptive profiles target game FPS and can reduce power use.
Per-game profiles support Steam, Lutris and Heroic.
Overlay displays performance, hardware readings and the active tier.
Imports MSI Afterburner curves and exports NVIDIA LACT configurations.

What to know first

Linux is the only listed platform.
Adaptive switching requires at least two usable tiers.
Tuning can hang the GPU, crash its driver, freeze the display or require a reboot.

Limits

Adaptive mode needs at least two usable tiers to switch between profiles; with only one, it runs that profile. Hardware tuning can hang the GPU, crash the driver, freeze the display or require a reboot.

Getting started

Install the proprietary NVIDIA driver and CUDA.
Choose an installation route: pip, Flatpak, Fedora COPR, Arch or CachyOS AUR, or Ubuntu PPA.
Install the root hardware service with the administrator prompt.
Create or select GPU profiles and configure tuning controls.
Add games from Steam, Lutris or Heroic to use per-game profiles.

Verdict

Choose PenguinBurner if you use Linux with a supported NVIDIA RTX card and want automatic undervolting, adaptive profiles or per-game tuning. Look elsewhere if you need a different platform, or if GPU tuning risks such as a driver crash or system freeze are unacceptable.

Questions

Is PenguinBurner free?

Yes. It is listed as free, with a free plan and no free trial.

Which platforms and GPUs does it support?

It is for Linux. The install guide lists NVIDIA RTX 30, RTX 40 and RTX 50 series cards.

What does it do for GPU tuning?

It offers automatic undervolting and overclocking, adaptive and per-game profiles, and manual voltage-frequency and fan-curve controls.

Which games and launchers can use per-game profiles?

The shared game library supports Steam, Lutris and Heroic. Profiles apply when a game launches and the standing profile is restored on exit.

What do I need to install first?

The install guide says to install the proprietary NVIDIA driver and CUDA before PenguinBurner.

How can users get help or report security issues?

The repository directs bug reports to GitHub Issues. Security issues can be reported privately through GitHub Security Advisories, or with a minimal issue requesting private contact if that option is unavailable.
