At least dfp is delayed in LFS too, not so much as in rFactor where delay surely feels to be quite massive, but in LFS there is more delay in effects than in GPL. I have heard G25 is lot faster, would be nice if someday I could test one.
But these delays I'm talking about are very very small, something like eye blink. I race quite lot LFS nowdays, but that is on my demo server 'Volvolandia' so it does not show in LFS world, however I have driven really a lot at blackwood and I know really well it already so I know what turns to make and what will happen next, only now I have started to notice these delays in dfp's FFB so they are rather small, however small things start to annoy when you constantly notice them.
Also that is how we are individuals, I'm sure other guys can feel lot differently than others, subjective things are something where there just is no truth, everyone has one truth that is true in their case.
When compared to my real car, LFS ffb is nothing like my real car feels, but this is issue with all games and sims, I don't think there is wheel or force feedback that would give same kind of effects what real car gives, it is completely different, so small things that you can feel and still so huge variance in power, it is very hard to even find words how to describe how real car wheel feels. I'm sure part of feeling is form how steering wheels effects whole body.
