sorry I mean before I launch the game , just chosing universe, or options and so forth, no mouse to start game, tab and enter works somewhat, but not well enough to change any game options
soon as you start launch from the rsi launcher you are in game. If you are seeing all the game options you already need to be in your HMD. You can tab around but at that point your mouse support is on your second screen which is you HMD.
Two different lines of your vorpx menu. First line is cinema mode, full vr or immersion mode. Next line down is your z-normal,z-adaptive, geometry 3d. With SC patch 3.1.4 geometry 3D is broke. Will not be able to use it. To bring up the menu use your delete key unless you have changed the default keybind in vorpx. You have a left and right arrow on these setting. click them with your mouse pointer to change them.
