I am using Unity 4.5.2f3 and SDK 0.4.2 and I can't get direct mode to work.
Any ideas ? I think you are using Unity 4.5.3 and SDK 0.4.1 right ?
I am not sure about what you say for the 60FPS in extended mode. The rift refresh rate is 75Hz so it should be the same in extended mode non ? My main laptop screen is 60FPS so I think it has to do something with that, no ?
I still have those ghost images when rotating my head !
