The FR3.5 is very low and loose in terms of FFB, especially around the centre. Try the Dallara and Formula ISI, it's quite different.

Between having the wheel feel exactly like a real car would, and missing all the info and positioning because my butt isn't on a race seat in the car at the track or having the equipment at home to fulfill that gap, and having the game transmit to me what the tires are doing, I will go with the latter. I can't complain about rF2 ffb.
