According to T4GR4, aka Steven Hood, on Twitter has said that the Understeer which has plagued wheel users may be fixed for the full game, fingers crossed:
Pre-release demos are always created earlier than you’d really want, simply because you have a big list of things that might be annoying you that you want to look into… but don’t have the time to resolve for an early demo. Add in the fact that tinkering with the demo means a retest and you can see why it can go out earlier than we might want.
It’s not as if we ‘fixed’ anything or found a problem – after the recent hands-on day in Southam we did pick up on a few comments to do with understeer. This had been bugging me for a while and had been something Lee and I were discussing. In amongst a billion other things we were doing at the time Lee trialled a couple of things and one of them worked really well. I won’t go into detail as to what it was/is but we much preferred the change. It makes quite a meaningful difference to the handling consistency, the grip levels and massively reduces understeer frustrations (especially so when racing). I hated the Lemo’s prior to this (I couldn’t find any consistency) but now I’m able to whip through them as I’d hoped. I stopped raging. It even improved FFB (to get where we’d like to be with this will take a little more work and therefore time but I was finally starting to feel the front tyres). We were getting a little too clever and, much like Jenson Button, decided to go back to basics and work up from there.
I’d like this in as soon as possible but perhaps more sensible types wanted to thoroughly test everything before making it available. We aren’t updating the demo and I can’t really say what our plans are with regards to the full game but simply know that I want this ‘change’ to make it through as soon as possible.”
