The whole steering lag thing seems to be a tricky one to fix. Some people have no problem whatsoever, others had it completely fixed with 0.73 and it still remains for many. I had massive lag issues with Shift2 but CARS seems fine for me. I'm sure they will nail it down eventually. Very frustrating in the meantime though.
The devs word on the gear change delay is that they are accurately modelling the gear linkage which means the cars do have this delay in real life. Many people have said this feels a bit weired so there's some discussion as to if it will remeain. I suspect those people with steering lag might also be getting the same thing with shifting too.
The odd thing was that it didn't immediately recognize the G27 properly. It listed G7 with separate pedals, but showed gamepad mappings. Cycling around it came back to normal, but it wasn't pre-mapped. Clutch is unassigned, and I can't change it.
With the new build I found it worked better by setting up a custom profile. If you look in the program folder there's also an alternate .exe that uses different FF code. It game me a good peformance boost but the FF felt slightly odd - some other people seem to like it though. I beleive that the clutch isn't mappable yet. While on track you can also press F1 to bring up the developer menu. This gives you access all sorts of technical stuff.
Is there a way to get rid of (or lessen) the fore/aft viewpoint movement when you hit brakes/throttle? I suppose I could get used to it, but I'd rather tighten the belts and do some neck exercises.
Yeah, i'm not keen on that kind of thing either. Hopefully we'll get the opton to change it in the future.
