Not to ruffle feathers, but I've noticed a of of really bad advice regarding setting up the G27 for this game (and others) - so here are my conclusions after several days setting things up to feel as real as possible. As I own an actual MX5, I have set the wheel up while using this in-game car. The worst advice I see is to set "gain" (i.e. overall ffb strength, set in game) at around 100 (or some people say 80-ish). IMO this needs to be pretty low (around 35%) or it's WAY stiffer to turn than any actual car. Nevermind if the ffb effects feel weak this low, this setting also affects how stiff the wheel is, and if the you have to struggle to turn the wheel, it's not going to feel real! In fact you're going to have real trouble controlling slides, or even just going round tight corners. I think a lot of people whack up the ffb strength to try and eliminate the floppy feeling around the centre of the wheel of the G27, but in AC there's a good solution for this: turn up minimum force to max (30). Even at 30, the wheel still feels a little unresponsive around the centre, so I keep this as high as possible - really helps give the wheel a more linear feel. I went in depth into the other settings too. So in the logitech profiler, the standard advice for years now (e.g. for Race07 etc) is: Overall force 100 (some say increase this to eliminate wheel's deadzone, BUT this will result in "clipping" or "spikes" in ffb (audio engineers will see a parallel here in boosting volume past 0 db) Spring fx: 0 Damp fx: 0 Centre spring enabled but at 0 Allow game to change settings. My conclusions: Leave overall force at 100. Don't want "clipping", and AC's in-game minimum force setting much better for minimizing floppy centre in wheel. Spring fx: 100 - if anyone can give a good reason to put this at 0, please let me know! It certainly doesn't mess with the real physics ffb, and as far as I can tell just allows the game to use spring fx for collisions etc. Damp fx : around 30 - in this game, this just adds some resistance to wheel when car stationary. You don't need much, I like 20. Again, no reason I can see to put this down to 0. Definitely leave centre-spring at 0 though (and if you do this I'm not sure it makes any difference whether the "allow centre spring" box is checked or not) Other in game settings: - don't seem to need any filter. All "canned" fx (road feel/slip fx curbs etc) all seem good around 25, though here I do think this really is a matter of taste - and as is pointed out elsewhere these are kind of "amplifiers", as these forces are already represented by the main ffb even if these sliders are at 0 - increasing past 0 basically gives extra shakes and rumbles when you go over a curb etc. Definitely helps feel more realistic with some of these extra fx dialled up a bit (a curb WILL shake the car!) but you don't need much. So in brief: Logitech profiler: Main: 100 Spring fx: 100 Damp fx: 30-ish Centre-spring strength: 0 Allow game to adjust: yes In game: Gain: around 35 Minimum force: 30 Curbs/roadfeel etc: around 25 Let me know if this helps anyone who's been struggling with an overly stiff wheel! Of course, if you prefer an overly stiff wheel (presumably because you also want stronger road feedback) then that's fine - but bear in mind that you'll have far more trouble controlling the car if the wheel is overly stiff to turn, so you're really not adding realism. Fact is, the ffb is far from perfect, and the floppy centre of the G27 is a real problem - but using this low "gain" setting, coupled with the high "minimum force setting", is the closest I've got the in game MX5 to feeling like driving an actual MX5. I'm also familiar with the Fiat 500, which also feels about right at these settings, so I'm presuming it'll translate to the other cars too.
