Hey Tony, I can only compare PCars in the Vive and AC in the DK2, but AC just seemed to be a bit more solid. The cars in PCars seem to be a little light and it's really easy to kick the wheels out if you are too hard on the throttle or the brakes. On the other hand, and being realistic about it, I really doubt I could throw a Lotus 49 or 25 around a track at speed and do a full race without spinning out or worse in real life and that's what I do in PCars in those cars now. Maybe it is more realistic than I give it credit?
I haven't run AC for a while but the visuals seem pretty comparable with PCars now being maybe a slight win over what AC was back when I was running it. The menus in PCars are way easier to navigate now than AC at least used to be.
Bruce will be able to comment on apples to apples today in the CV1, though.
But I had forgotten how fun racing is in VR since AC had dropped off the VR radar for a while and until PCars added support for the Vive. I'm getting a handle on the cars now and it's huge fun.
