Question 1

How to install Gamescope on Ubuntu?

Accepted Answer

Gamescope can be built from source using meson and ninja, as per the README instructions, or installed via packages listed on Repology for various distributions. Check your distro's repository or build from Git submodules.

Question 2

Does Gamescope work with NVIDIA graphics cards?

Accepted Answer

Yes, but it requires NVIDIA proprietary driver version 515.43.04 or later and the 'nvidia-drm.modeset=1' kernel parameter to be set. Ensure your system meets these requirements for proper functionality.

Question 3

What's the performance difference between Gamescope and Mutter for gaming?

Accepted Answer

Gamescope is optimized for low latency by minimizing frame copies and using async Vulkan compute, while Mutter is a general-purpose compositor with more overhead. Gamescope is better for gaming-specific performance, but Mutter offers broader desktop features.

Question 4

Can I use Gamescope to limit FPS in Steam games?

Accepted Answer

Yes, set the Steam launch arguments to include gamescope commands like '-r 30' to limit frame rates. For example, 'gamescope -r 30 -- %command%' caps the game at 30 FPS, as shown in the README examples.

Question 5

How to set up ultrawide gaming with Gamescope?

Accepted Answer

Use the '-w' and '-h' options to set the game's resolution and '-W' and '-H' for the output window, along with '-b' for borderless mode. For instance, 'gamescope -w 1920 -h 1080 -W 3440 -H 1440 -b' pillarboxes a 1080p game on a 3440x1440 display.

Question 6

Is Gamescope's Reshade support good for CRT shaders?

Accepted Answer

Gamescope supports a subset of Reshade effects via command-line parameters, but it increases latency due to compute queue usage. It's suitable for non-critical effects like CRT shaders, but for low-latency needs, consider alternative methods like LUTs.
