## Apps with GameMode integration
### Games
The following games are known to integrate GameMode support (meaning they don't require any additional configuration to activate GameMode while running):
* DiRT 4
* Rise of the Tomb Raider
* Shadow of the Tomb Raider
* Total War Saga: Thrones of Britannia
* Total War: ROME REMASTERED
* Total War: Three Kingdoms
* Total War: WARHAMMER II
* Total War: WARHAMMER III
### Others
Other apps which can integrate with GameMode include:
* [ATLauncher](https://atlauncher.com/downloads) Minecraft launcher
* [Cemu](https://cemu.info/) Wii U emulator.
* GNOME Shell ([via extension](https://github.com/gicmo/gamemode-extension)) - indicates when GameMode is active in the top panel.
* Lutris - Enables GameMode for all games by default if available (must have both 32- and 64-bit GameMode libraries installed), configurable in preferences.
* [Prism Launcher](https://prismlauncher.org/) Minecraft launcher
* [RetroArch](https://www.retroarch.com) - is a frontend for emulators, game engines and media players.
