It suddenly hit me today after driving race 07 that in rfactor there is no settings to put force feed back on for the brakes. In race 07 this can be setup so that the wheel would have a rumble under braking and as soon as the car wheels locked up under braking the rumble stops telling you to get off the brakes a little to release the locked wheels. So can we have this or something similar
What about this in the controller.ini ? Brake effects on steer axis="0" // 0 = Brake effects on brake axis, 1 = brake effects on steering axis. I think it was on by default in rF1 with full FFB, but if I recall correctly from the couple of times I accidentally left it on I think it worked in the reverse manner to what you're describing - it would start doing something when you locked up. Note: I'm not sure it actually works. I've never tried it.
I tried changing that setting in the ini file but I feel no vibrations with braking. I would really love to have this FFB effect implemented. It was great on race07. Please consider adding this ISI.
