Why dont you ask Logitech?
I have... but the response has been an automated reply.
You made the decision to buy a wheel that is PS3 and PC compatible. The one to blame here is yourself. Either buy a new wheel or play with controller.
I bought the G25 LOOONG before the XBox 360 ever came out.
And before that, I bought the Logitech Momo racing wheel.
And I also bought the original MS Xbox 360 wheel and pedals when Forza 3 came out.
I've been using the G25 on my PC to play GT Legends, GTR, GTR2, F1 Challenge 99-02, rFactor, Race 07, GTR Evolution, and NASCAR Racing Season 2003.
I also have been playing GT5, Shift 2, and F1 2010 w/ my G25 on PS3 without much issue.
However I usually end up using my XBox controller when I play PGR, PGR2, PGR4, Race Pro, Shift, Forza 2, Forza 3, and GRID.
Yeah.. I've been racing computer games since the days when Papyrus was the major race sim developer.
So saying I have myself to blame? Yeah.. I blame myself for purchasing one the THE MOST PURCHASED racing wheels in the history of racing sims. I blame myself thinking that a manufacturer actually WANTS you to continue using their products. And I blame myself for replying to ignorant posts like yours.
