Rendersize (Slash Command)

Slash Command

/rendersize x y

Changes the size at which the 3D world is rendered

Partially functional command.

X and Y are the horizontal and vertical resolution or render size of a display. For example, 1920x1080.
This command changes the resolution of everything that is rendered in 3 dimensions by the graphics card. Conversely, it does not affect 2-dimensional objects rendered by the game such as the chat box or other User Interface (UI) elements.
Any render size set by this command is overridden and reverted as soon as the Graphics and Audio tab in the Options window is activated. Further, there is no "Render Size for 3D Graphics" setting in the gfx.json graphics settings file. So it's very possible this command is obsolete or has been depreciated.

The command can be run automatically at log-in as a Command Line Parameter. For example,
-rendersize 2560 1440

/rendersize 2560 1440
