It's not possible to integrate commands like optirun automatically inside GameMode, since the GameMode request is made once the game has already started. However it is possible to use a hybrid GPU wrapper like optirun by starting the game with `gamemoderun`.
You can do this by setting the environment variable `GAMEMODERUNEXEC` to your wrapper's launch command, so for example `GAMEMODERUNEXEC=optirun` or `GAMEMODERUNEXEC="env DRI_PRIME=1"`. This environment variable can be set globally, so that the same prefix command does not have to be duplicated everywhere you want to use `gamemoderun`.
You can do this by setting the environment variable `GAMEMODERUNEXEC` to your wrapper's launch command, so for example `GAMEMODERUNEXEC=optirun`, `GAMEMODERUNEXEC="env DRI_PRIME=1"`, or `GAMEMODERUNEXEC="env __NV_PRIME_RENDER_OFFLOAD=1 env __GLX_VENDOR_LIBRARY_NAME=nvidia env __VK_LAYER_NV_optimus=NVIDIA_only"`. This environment variable can be set globally (e.g. in /etc/environment), so that the same prefix command does not have to be duplicated everywhere you want to use `gamemoderun`.
GameMode will not be injected to the wrapper.
