Depending on the direction of the wind you can get more, or less downforce, which in some corners will affect your line. Not by meters, but it can definatly change. And setup as well, of your rear end is loose, then you'ld like to brake much straighter, maybe steering in a bit earlier, and drive straighter to the clipping point. Or go in a straight line to the outside, then steer a bit tighter, too accelerate straighter. Now if you have a car that generates understeer, you'ld drive that turn completly different. I don't know if you've seen f1 in austin. But the corner where Button overtook quite a few drivers, is a nice example where I think in some cars you can drive multiple lines, depending largely on setup. Maybe not so much in a f1 car, but in some cars I'm sure it will differ. At least, that is my opinion (or lack of skill forcing me to drive a bit different possibly, you decide )
