I thought about trying Iracing for the first time and started to watch some videos and setup but I'm having an issue. The video I watched had the ffb turned off to calibrate the wheel. I cannot find this option in logitechs gaming software. I find an option to turn it down but not off. Has anyone else experienced this? Is it alright to calibrate it while the ffb is active? Or should I turn it down all the way? Or am I just missing the option of turning it off?
