Question: What command line parameters can be used in Max Payne 3 for PC?
Answer: Below is a list of supported command lines. Commandline parameters can be added to the "commandline.txt" file in the root of the game folder. To create this file, right-click inside the directory and navigate to New->Text File (or create and save a text file of this name using wordpad). Then name the file "commandline.txt" (without quotes, and some players will need to just use "commandline" without the ".txt" at the end).
For Steam players, rght click your game->Properties->Set Launch Options->Type the commands you wish to use.
Be sure to include the dash at the start of each line.
