Same here, rF2 beats all. I only have pCars installed for guests to show real VR, that's it. I am able to run it in CV1 using software called vorpx. It is not like native support in games you listed, but it works and is a nice alternative to triple screen setup. What you get is basically mouse look by head tracking and fake stereo vision, which is almost useless honestly. See post 432 for basic steps outlined. I also use joy-to-key software to zoom in/out in vorpx from wheel. Even if rF2 gets native support in the future, vorpx will come handy with rF1 and GTR2/PnG.
This project is dead. You only have to wait a few days/weeks to get native VR support in rF2. This project was good in DK1 and early DK2 days without native VR support.
