I have been thinking for a long time about feedback to different wheels ni different games. Momo for example is very powerful but also quite lazy in most games (from my experience). Atm, I have a Logitech df gt and it is a great wheel, very responsive and very powerful - until I started driving in iRacing. Compared to G25, totally unresponsive. I can't drive the Solstice or Lotus 79 with it. Not fast at least
We just finished 2h endurance on FRL with UFR. I had to reduce ff to 40% just to feel my arms at the end
Feedback in LFS is excellent but as someone wrote... if the tracks are not bumpy you cant feel the bumps, just the grip (or the lack of it)
