So, tonight I took on some pCARS in a McLaren 12C GT3. It’s late so I made some mistakes. It might be good for some laughs. https://www.youtube.com/watch?v=TQ28jRP2_RI
While I was playing though, whenever I’d drive in a straight line, with the wheel perfectly centered, the wheel would begin to shake violently. It would stop as soon as I put pressure in any direction on the wheel. I went into settings because I thought maybe there was a dead-zone assigned to the wheel causing it to act that way, but no. Dead-zone was 0. I did think to recalibrate it, and that solved the issue, so if you run into that issue try the calibration, and let me know if that works for you.
