Alright so forget everything the guide says to do, you just want to right click on the game's executable and click "Create Shortcut". Then right click on the newly created shortcut and click on properties, it will already have the target field highlighted when the window pops up so be careful not to type anything while the text is selected or else you'll accidentally lose it, just press right arrow to unselect the text but leave the text cursor right where you want it. Add a space and then type in the launch argument (without the speechmarks): "--rendering-driver opengl3".

So now when you open the game via that shortcut it will do that whole CMD process by itself. If this continues to be an issue for many players, the dev could really benefit from making this shortcut themselves and putting it with the game download.
