OK so comparison between the two is a bit chalk and cheese. I got F1RS
and the demo GPL over Easter and switching between the two I definitely
get the impression that the car in F1RS "floats" along the track whereas
GPL appears to model vertical movement much more effectively. After
watching the real racers crashing across the bumps in Argentina the same
weekend (especially that one bump before the back straight), maybe this
is a weak point in F1RS and a reason why some rave over the GPL.
