I might as well add my thoughts on the FFB now I've had PC3 a few weeks. I go along with what
@Scaff says in in his video up top. Particularly about the wheel shouldn't be difficult to turn, but each to their own likes in that really.
Now I'm coming from PC2 so if you're not you may not know some of the terms.
I think PC3 uses the informative flavour from PC2 as standard, there's no other option. Or a slight variation of informative at least. Therefore there is no gain setting since this will be at 100% and then, depending on your settings with the sliders, the auto adjustment will smooth the output to the wheel to prevent clipping of FFB signals. Probably, although it doesn't mention it*, I'm assuming it takes a few laps to adjust to setting changes as previously.
*It doesn't mention anything! I know it's supposed to be more jump in and play than previously but a little explanation to the settings would be appreciated, especially by newcomers.
The strength setting is the same as volume in PC2 - the resistance to turning and centring force of the wheel.
The tone is the same as previously - Road bumps and suspension feel to tyre and surface feel.
The vibration replaces the FX slider - Artificial kerb and other effects to add "excitement".
The menu spring strength is the same - How fast the wheel rotates to centre from an offset position when you return to a menu screen.
And my current G29 settings for reference.
Strength 35 - Easy to turn and catch slides and also allows other effects to shine.
Tone 70 - The increased tyre feel can add a little extra weight on certain cars and again makes slides easier to feel.
Vibration 10 - Too much makes my gears rattle. That's the gears in my wheel not in me.
And brake sensitivity turned down (still experimenting). The G29 has a limited travel range in its brake input (it's calibrated to the rubber bung they fitted) so I find lowered brake sensitivity helps. PC3's cars can be a bit snatchy anyway.
