Geometry does not work but you can get 3D working in BF3….a little trick that worked for me was to switch from Rift mode to side by side mode then back to Rift mode in your pop up settings menu. Not sure why thats needed but it works for me. Not the best 3D but good enough.
The options have rift and riftSBS. I started it up, and switched to riftSBS, pressed ok. Did nothing. Switched back to rift. Nothing. Played with it, couldn’t get it to do nothing. Meh I would love to get this to work.
Just tried it in multiplayer and it works…use flawless widescreen to adjust FOV. Like I said it has good 3D ..The Rifts resolution prevents me from playing multiplayer. Try using Z adaptive in the settings
