Usually this is part of the issue, people pushing hard enough. More often than not, driving the cars far too hard. Exercising hard and very late breaking, jerky and excessive steering, and mashing the throttle out of the turns. It all has a negative effect on the handling, causing big shifts in the weight of the car. Weight transfer is something that Forza handles very well. Horizon is vastly more forgiving then Forza Motorsport, but not by that much. If you poke the cars with a stick, they are going to bite you. Just like a real car would. More often than not, most peoples problems with the handling; can be solved by slowing down. Ditching the constant late breaking, keeping steering movements as smooth and direct as possible; and rolling the throttle back on out of the turns.
Ive used my G920 and a T300 with FH4, and both work very well. The driving in this version of Horizon is an absolute blast on a wheel. Not saying there are not improvements to be made, every single racing game out there needs improvements in wheel functionality. But to say that FH4 is unplayable on a G920 (or any wheel for that matter); is a gross exaggeration.
