I don't know why or how, but I forgot about this KartSim thing until the most recent update about it. I finally gave it a try and I'm really enjoying it. This is the first session I've done with these Karts, they immediately feel much better than what I remember of the old ISI karts and once you get a feel for them, they're incredibly fun. I have to use 25% smoothing to keep my wheel from oscillating like crazy but that allows me to use 100% FFB strength, which I feel is necessary to be able to feel what's going on in these.
