Brand new SC2 Sport has really nasty vibrations in iRacing

Simucube 2 Simucube 2 Questions

Like the title says, I am getting really bad vibrations in SC2 Sport when trying to use it in iRacing. It happens in all cars, but the stronger the FFB the more crazy it gets (video below is in Dallara ir18 to accentuate how bad it gets). Is this a normal issue? Are there settings I can change to get rid of this issue? Because this is basically unusable at this point.

Video of Vibrations:

iRacing settings: Damper, Min Force, etc set to 0. Wheel force set to 17nm and strength set to 10.

Try increasing inertia and friction.

Its a known issue that is specific to the IR-18 car with new 360 Hz mode in iRacing. The vibration is in the 360 Hz signal itself.

You can try to turn off the ultra low latency mode also. Or turn off the 360 Hz mode in the app.ini.

Put slew rate limit to 0,1

Hey, umm this is actually identical to the issue I am having with my new Simucube Pro 2 in ACC. I’ve just opened a thread about it :slight_smile:

Hi, I have to report the same issue in the new IndyCar in iRacing. Sometimes I get the same vibrations when the car is moving, and the vibrations stop when I stop the car completely.

I solved the problem when I changed the Simucube FFB from 360 Hz to 60 Hz.

I would just like to report that problem with the IndyCar and 360 Hz is not solved by Simucube/Iracing yet.

Regards

Yeah, I don’t think iRacing is now actively trying to solve it, since they are very focused on refactoring their game engine to support true higher FFB rates. Even if they get to e.g. 180 Hz, then we can probably drop out all the 360 Hz modes since the improvement would be already huge.
