This isn't every option I have changed but I highlighted the important ones. Yellow are optional tweaks. The flow lines change how smoke and fire act around your car and others, The backfire anim is WAY too slow by default and some of the rear view mirror settings for distance rendering improvement. Orange are the big changes. Mostly to do with the "feel" and movement inside the cockpit including but not limited to high speed shake, Look ahead prediction and rear view FOV. Here's a video of what some of these orange settings can do if you screw with them too much. :tongue:CAUTION.. Avoid fullscreen if you get motion sickness.
