It is working good with my G27. I can feel everything and i am using Simulation + force feedback in 5 'only' because 10 is way too heavy.
Do a lap in Nurburgring to check that again.
Still since 2.00 or 2.01 physics changed a lot and the FFB feels different since then.
Wheels should have more options as PC simulators or even as NFS Shift, pCARS or Dirt series has. Despite the physics at least you can set the wheel as it should be. Death zones, degrees, FFB, speed sensitivity...etc.
I always feel that the FFB and the overall response when i play with my G27 on my PS3 is way too low and different comparing it to games on PC. It is like the PS3 gives less power to the G27 FFB engines than my PC gives. (it seems! i am not sure if this is real or not but i am sure that the same game on console feels different than the PC version)
On PC feels better of course.
GT5 has some issues with physics still. Frictional force for example. If you put a car in one of the main curves at Route X you will see that the car starts to slip over the track as on ice. And that is not realistic at all. Maybe in wet conditions but not with dry surface.
