Is the Rift easy to use?
I've been holding off as it's only DK, so I thought it might be out of my knowledge base.
It would help in my miniscule unit not to need 3 screens.
It isn't difficult to setup. Just a bit fiddly at the moment. DK really only refers to the stage of development rather than how easy it is to use. It is the OS and application support that is still really in its infancy.
I think it still needs a strong graphics card so I wouldn't see it as a way to avoid upgrading to a triple setup. Even though it is only 1920x1080 resolution it is rendering two images and doing full 3D and low latency and frame rate is critical. The amount of graphics detail is amazing.
Also, the Rift is not ready to use full time in Assetto Corsa. There are no menus so you can't select setups, check other driver laptimes, see split times etc. You can't tell if you are in practise, qual or race mode and cannot tell how many laps are remaining. The problem is that you cannot get this information inside the Rift world and you cannot take the Rift off and read that info from your normal monitor.
Basic menu and info screens will come pretty quickly. But I think it is going to be a period of experimentation for Kunos as they try and work out how to integrate the user programmed apps into the VR world. They have a software architecture problem in the way they overlay the menus on the driving screen. Those menus are not part of the actual simulation engine from what I can tell. So Kunos has to develop a whole new menu and information system that is visible and selectable inside the Rift world. LFS could do VR Support quickly because their menus were already rendered as part of the simulation engine,
I'd be happy with a basic HUD inside the Rift showing laps, time, session type and track map - something like a Motec. All other selection menus could just be displayed on the normal screen. Then you just take off the Rift to select a setup etc.
