[shake_n_bake]

How can you view replays in grid in slow motion on PC? i know you can do it on the 360. but on the PC you only got paused, normal, and fast. when u go from paused to normal it goes slow for a second but then picks up, i wana know how to keep a constant slow motion anyhelp plz?

I use my 360 controller and can just adjust the steering stick slightly and voila.. slo-mo.
