Gamescope With NVIDIA

Ever have a game ignore your display settings? On my system Trackmania 2020 has two display modes. 1080p windowed and 2160p fullscreen. Gamescope can help with that by putting games into obey me mode. It even works with NVIDIA, doesn’t it?


Speaking of drivers, you will need version 515.43.04 or above. 

Massaging Grub

Before doing anything you need to add nvidia-drm.modeset=1 to grub, update grub, and restart the PC.

sudo nano /etc/default/grub

Updating grub

sudo update-grub

Clone the git repository 

git clone

Change into the gamescope directory and update the submodule

cd gamescope ; git submodule update --init

Invoke meson build

meson build/

Build gamescope

ninja -C build/

Install gamescope

sudo meson install -C build/ --skip-subprojects

Running gamescope

Configure gamescope by right clicking on the game, selecting Properties, and editing the launch options under general settings. You can save some time by installing Steam Tinker Launcher.


Rendering a game at 1440p and upscaling it to 2160p (borderless fullscreen) using AMD FSR with mangohud enabled.

gamescope -h 1440 -H 2160 -U -b -- env MANGOHUD=1 %command%

Rendering a fullscreen game in a 1080p bordered window

gamescope -h 1080 -H 1080 -- %command%

Useful options

-U, --fsr-upscaling            use AMD FSR 1.0 for upscaling
-Y, --nis-upscaling            use NVIDIA Image Scaling for upscaling
-i                             use integer scaling.

-b, --borderless               make the window borderless
-f, --fullscreen               make the window fullscreen

-w, --nested-width             game width
-h, --nested-height            game height

-W, --output-width             output width
-H, --output-height            output height

Super + F                      toggle fullscreen (DANGER) 
Super + N                      toggle nearest neighbour filtering
Super + U                      toggle FSR upscaling


In 2023 gamescope + NVIDIA is a good experience. No performance regressions (or boosts) to report and things seem stable. Well, if you ignore Super + F locking my desktop.
