It would be very helpful to have hotkeys for adjusting FFB strength up/down while in-game. Project Cars 2 & LFS are good examples of this functionality. Showing the increment in the UI would be excellent as well. Example, the player is driving off-road so they want lower strength temporarily. They could hit the < key a few times with the UI indicating "FFB Strength: 220", "FFB Strength: 180", "FFB Strength: "140", or whatever increment is logical. This would be much quicker than going into the nested menu each time you change vehicles or driving scenarios.
