It's true that developer Evolution Studios toyed with Sony's new virtual reality tech when developing the PlayStation 4 exclusive title, Driveclub .
However, Sony Worldwide Studios president Shuhei Yoshida clarified to GameSpot that this was not the reason the game was delayed.
For the record, Driveclub won't be compatible with Sony's VR tech, just revealed as Project Morpheus . Yoshida said he tried it and while it worked well at low speeds, higher speeds brought on the difficulty…and the motion sickness. Therefore, Evolution "is not working on Morpheus at all" and they're putting "all their effort" into completing the game. It still doesn't have a solidified release date, but let's just say it's a ways off.
VR racing? That might be the only form of VR I'd try, but I doubt I'd last very long.
