I'm about to try it out right now. Sadly, I'm probably going to be dissapointed
I think I'm buying a G29 tomorrow, but the intriguing response from Kaz about supporting old wheels like the DFGT is making me have second thoughts.
The interesting thing is that the DFGT is the only PS3 wheel that had a PS button. The PS4 needs that buuso you can tell it what controller you are using. The PS button on the DFGT does nothing when plugged into the PS4 (I tried it) so I there os no way it would work in any game right now without something like the GIMX that lets you map buttons.
