I really hope they get ‘Direct mode’ implemented the right way and that with that all the ‘multiple desktop’ / primary / secundairy / refresh rate issues are solved.
Extra great would be if they allow somehow to make a secondary camera / allow somehow to implement a 3th screen with instructions to put on the headset or even a overview of the game (Like they talk about in Gamasutra - Q&A: Oculus' software guru sheds light on the new SDK driving DK2)
Sure there would be some ‘performance considerations’ but having the option would be awsome.
