Haven't had any crashes on any of these test patches, new shadows are nice, bit of a fps decrease but other than that 100% for me anyway.
I know this is off-topic but the dev's must feel pretty rubbish when half there community start moaning and crying over abs being added to the road cars, I'm sure it was a lot of work and time went into the creation of it and when people basically asked that they want an option to disable it (I can understand for leagues) it must feel pretty rubbish...
I personally use a mouse and I find that it is helpful but overall doesn't improve my times but the key point is it's helpful to some people so I wish people would stop moaning at the dev's, it's there game and they can add what they see fit.
