I never noticed input lag...
Anyways, the game is pretty enjoyable - when it comes to racing. It feels a bit unrealistic at times (f.e. I'm hittinga corner at a normal speed, entering it works like a charm, but as I try to exit it, I have to countersteer); Also the FFB is really not good - But that could be because I have to use the G27 preset. The g25 one doesn't work, because ea was so wise to not set the accelerator on the right pedal, and not making me able to change buttons at all.
BUT, the big but, is drifting. I've never seen such bullcrap in my life. There is absolutely no grip, but sometimes the car still grips a bit and turns into the other direction. Also, Wheelspin while starting from 4th gear a Nissan 240SX? RIGHT, way to go EA.
