Sony Worldwide Studios president Shuhei Yoshida told GameSpot this week: "There's a rumor the reason of the push back of DriveClub was to make it Morpheus compatible... that's totally untrue."
CVG revealed last September that Sony-owned Evolution Studios was working with Morpheus to simulate a cockpit view on DriveClub, something Yoshida admitted this week, although the experiments proved unsuccessful.
Yoshida said DriveClub VR worked well at low driving speeds, allowing users to enjoy the passing scenery, but that it was "kind of difficult and sickening" at higher speeds.
Right now, Evolution is "not working on Morpheus at all", instead focusing its efforts on completing DriveClub, he added.
The game was originally meant to be a PS4 launch title, but in October 2013 the racer was delayed to a vague "early 2014" window.
Sony Worldwide Studios America software product development boss Scott Rohde said in early March that the game had needed to "go back to the drawing board".
He explained: "It all comes back to that fundamental principle, and that's that we want to build great games. And we really don't want to release a game before it's ready.
"Sometimes, this happens in the normal course of business, where we think we're on track to deliver what we think is going to be a great game, and when we get closer, we realize that we'd be doing everyone a disservice if we shipped it before it was ready.
"So, I think that at PlayStation, perhaps more than at other places, we're willing to kind of eat that [cost] and go back to the drawing board and make sure the game is great before we ship it. And that's what's going on right now with that game."
Last week, Amazon's US arm began listing the DriveClub release date as Tuesday September 30, 2014. The retailer also reportedly began informing pre-order customers via email when they can expect to receive the game based on "a new release date" supposedly supplied by Sony.
We sought an update on the DriveClub release date from Sony last week but the publisher opted not to comment on the Amazon information.
