How does the steering feel at those uppers speeds?

Feels just fine to me; but I am not an expert. It's responsive, yet not "twitchy". I would say it's on par with my previous M3 steering feel, driven normally. I was running with all systems on "normal" and did not have the Sport or Sport + on.
I see lots of complaining about the new X3 steering feel on here, but I don't find it a problem at all. I am happy with it, but maybe I'm not enough of an "enthusiast" to offer that opinion.
