Well I had wheel oscillation problems when I first installed LFS, and those settings fixed them. I kept them that way because I didn't know any better. Now they're fixed and the road feel is even more fantastic than it was before.
To Greboth,
Of course you would feel bumps through the wheel, a percentage anyway, in any racing suspension.
As a mater of fact, that kind of wheel feedback is extremely important, to feel the road.
About vibrations, well those are engine enduced, and still reflect on the steering column in a lot of cases. Especially smaller cars, usually open wheel, where there is less dissipation of the vibration trough the chassis.
I have nice resulst with setting Control panel options at 80% FF, and then about 130% in LFS. This makes steering a bit harder, but in my opinion closer to track feeling.I cant yet comment on bumps, vibration etc, but Im a bit happier now.
Still think a few triggered FF effects should be added in S3, that would add to the experience.
Again, you get vibration moving through the chassis, into the steering column and from the steering column into the steering wheel. Again this is vibration. Vibration does not cause your wheel to spin back and forth. It causes your wheel to.... vibrate. Vibration is not occillation of the wheel. Unless you have vibration on the PC wheel controller, you cannot feel vibration on your force feedback wheel which only transfers forces acted on the wheels in a lateral direction to the force feedback.
This is most unfortunate. And some of you should get off your high horse about "faked" FFB. What's fake is missing half the forces you would normally feel through the wheel and that are necessary when you are sitting in front of a PC screen with zero G forces to guide you.
The FFB that is in LFS is nice...they just need to add the rest of the missing elements to make it wonderful.
The other thing that I do find "fake" in LFS is the visual effect of running over some rumble strips (the quite effective shaking sensation of the entire screen image) while feeling nothing through the FFB wheel. The visual andf the FFB should go together 100% of the time, but this is just part of the inconsistency in FFB with an iForce-based (Logitech and others) wheel.
