I wish you had to use the clutch in every gear. It seems once your out of first you can just shift without the clutch. It would make it a lot more realistic if you didn't properly engage the clutch you miss the gear.
There is a big thread about a realistic clutch here: http://isiforums.net/f/showthread.p...nclude-a-realistic-clutch-option-in-rFactor-2 ISI already confirmed to improve the clutch simulation for more realism.
