RRe is satisfactory when you dont play other sims, however back to back with other sims rre shows its awkwardness in ffb.
I agree with this. I have a Thurstmaster TX, and experience both the floatiness/hovercraft effect, and the over aggressive recentering (which often overshoots the mark, leading to a bit of oscillation). Some cars are worse than others.
If I play R3E exclusively for a few days, I begin to adjust and it isn't as bad (still noticeable and disruptive, but manageable). But, anytime I go to or from another sim (AC, GSCE, rF2, GTR2), it is very obvious and takes a while to readjust. None of the others have these issues and, although they each have their own feel, don't require much of a readjustment period when switching from one to the other.
I spent a few hours over the weekend playing R3E only (ADAC '14, mostly with the McLaren, which I find has less of this problem then most). I had a lot of fun, but these issues were a distraction. Additionally, my wrists and shoulders were a little sore from constantly fighting the centering/oscillating. I'm using settings based on what one of the S3 guys posted (I forget who), but I've tried pretty much every combination imaginable at this point. I've also tried tweaking every setting in the TX control panel.
I also agree with what Brandon Wright posted above that the floatiness is exacerbated by the lack/quietness of tire squeals (I've tweaked the audio levels as well, and still have difficulty hearing tire squeal). I have a feeling that it also has something to do with the visual aspects of the game, but I can't quite put my finger on what. I don't know if it is head movement, a lack thereof, or what, but something about the look when going through a tight turn with a little bit of sliding/slip angle going seems a little off. In total, it just seems like the various senses aren't completely in sync or quite as I'd expect (from other sims and real life).
All in all, I really enjoy the sim and think it has great potential. I just hope they can iron out some of these issues, or at least figure out why they seem to affect (or bother) some and not others. I've not played it as much as I would otherwise, which also means I haven't purchased as many add-ons as I otherwise would have.
