Usually in games the game view is mirrored but the cursor is not and the center of the +game which is normally at the center moves to 1/4 and 3/4 of the window. With --cursor-wrap, the cursor position in VR will match the real position of the +cursor relative to the window and with --no-cursor-wrap the cursor will match the position of the cursor as the game sees it. + +Note: --cursor-scale is set to 0 by default in 180 degrees stereoscopic mode and --no-cursor-wrap is set by default in --flat mode. + # Games This vr video player can also be used to play games in VR to to get a 3D effect, and even for games that don't support VR.\ For games such as Trine that have built-in side-by-side view, you can launch it with proton and there is a launch option for side-by-side view.
