The Games Smurfs 2 is starting SteamVR on every Launch.
Unreal Engine has its VR plugin turned on by default and I guess the developer just forgot to turn it off since the game has no VR support.

This happens with the GOG and Steam versions of the game.



Workaround:
just add "-nohmd" as launch option.


on GOG:
- in your "Installed" Tab right click on the game
- select "Manage installation" > "Configure..."
- go to "features" Tab
- check "Custom executables / arguments"
- duplicate the default argument by clicking "duplicate"
- in the new set (File 2) add "-nohmd" to the Arguments (without the "")
- check "Default executable" for File 2
- save by clicking "OK"


on Steam:
- in your Steam Library right click on the game
- click "properties"
- add "-nohmd" into the launch options (without the "")


Now the game should start without launching your SteamVR.
