A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]
I find it difficult to make per game configurations. Ex. gamemode.ini with a custom script for 4:3 stretched resolution for CS2, but a different custom script for other games. This would also help with organization of config files.

Describe the solution you'd like
A clear and concise description of what you want to happen.
GAMEMODE_CONFIG environment variable should take precedence over all other config file locations. The would allow for steam launch options such as: GAMEMODE_CONFIG=~/.config/gamemode/gamemode-callofduty.ini gamemoderun %command%

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
Trying to find $PWD and put the config file in that location for steam games.

Unfortunately this doesn't quite work in the current logic, even if code were implemented to pass the config over the dbus connection to the daemon - in particular because gamemode is itself a "global" on or off mode, I don't think there'd be a way to selectively activate certain settings like that.

Unless the code has changed since I wrote it! Perhaps it could be possible now in some form.
