FAQ: Rendering at monitor or custom resolution

"Display Size" to match the native resolution of your display



"Custom" to set a custom resolution

(Update: these instructions were way out of date. This thread used to be called "Fullscreen not rendering at monitor resolution")In the launcher, go into "Advanced Options" and select:NOTE: if you're running with Render Quality set to Low, or set to "Use Defaults" on a laptop with an integrated gpu (e.g. Intel HD Graphics) changing this might give you poor performance.------------------------The old workaround using the launch options will still work if you prefer that :In Library in the steam client, right click on The Witness and go to:Properties -> GENERAL -> SET LAUNCH OPTIONS...set the options to:-width 3440 -height 1440(or whatever resolution you want it to render to)
