I bought a second hand Rift CV1 on the strength of seeing videos of people using it in sims such as LFS and AC. It is a game changer for me as it really makes a difference when going wheel to wheel with other racers.
Also you end up naturally pointing your gaze towards apexes and exits of corners, which has made me a much faster driver than dealing with a monitor display.
I had my own Ronnie O'Sullivan moment shortly after getting the Rift, I was in AC racing the 1960s prototypes around Monza (the configuration covering the original oval and road course against CPU opponents in VR. One of the other cars clipped me coming out the last banked corner, sending me in to the barriers and barrel rolled. I ended up curling up in a ball (bear in mind I am 1.82m tall around 124kgs and sat on a rotating office chair), chair twisted round and I jarred my back....
Had to go see the doctor and ask for painkillers... poor doc did not have a clue what I was going on about lol!
I have learnt my lesson and bought an FK sim rig so I have a proper seat and a nice mounting position for the wheel instead of a desk and swivel chair I was using before
Once I have the funds I do want to upgrade as the resolution is pretty low, but I definitely got the bug for VR!
And by being the first sim to do VR right, I have to commend Scavier for taking the time and implementing it.
I think that multi core support would work really well with LFS, and use the extra unlocked cores for things like improved AI and possibly help with the tire model i.e. it can work to a higher frame rate or even improve the car damage physics i.e rebuild the cars with crumple zones for newer models and make them deform even more like real life cars.
