VRC secret config menu When developers make games in the Unity game engine, Unity will create a configuration menu when the game is launched. (this is stereotypical with shovelware Unity games) The developers behind VRChat have this disabled, But there is still a way to get this to appear: Go onto Steam Press the LIBRARY tab Press & HOLD down SHIFT key Launch VRChat whilst keeping hold of SHIFT DO NOT LET GO of SHIFT untill the menu appears! 　　　　　　🛈　CONFIG　MENU　PARAMETERS　🛈 　--　SCREEN　RESOLUTION　-- Change the resolution that VRChat starts in. This goes from 720p and beyond. But I have seen this go lower on past occasions. Regardless, you can edit these parameters by inserting these into the command line: -screen-width [WIDTH] -screen-height [HEIGHT] 　--　GRAPHICS　QUALITY　-- Change the graphics quality for VRChat. Początkowo opublikowane przez RekoRed_: In more triple-A games this will have a massive boost in framerate because most triple-A developers will have different levels "sets" of models, textures etc. Unity may perform some under the hood adjustments depending on the graphics setting but since most of the game is made by other users, this may not be the most efficient. 　--　SELECT　MOINTOR　-- Want VRC to run in a diffrent mointor? No problem!
