options.lua ["OculusRift"] = false, (<- what's this?)

I was playing around in VR and noticed this line in my Options.lua file. But I don't see any option to turn it on/off in the game. What is that? I have OR so I am curious..

["graphics"] = {
	["DOF"] = 0,
	["HDR"] = 0,
	["LensEffects"] = 0,
	["MSAA"] = 0,
	[u][b]["OculusRift"] = false,[/b][/u]
	["SSAO"] = 0,
...

I did change it to true, but I didn't notice any difference..

Originally DCS Started w/ Only Rift Support, then Moved to Rift + SteamVR/Vive.

That string has been replaced, however since /Saved Games/ Folder isnt touched by updater, the options.lua still contains the line, you can delete the options.lua and let DCS Generate a new one, in which case all old strings would be removed, but you'd have to re-set all you settings.

Since been replaced w/ Global VR String:

["VR"] = {
	["box_mouse_cursor"] = true,
	["enable"] = false,
	["pixel_density"] = 1,
	["use_mouse"] = true,

Thanks!
