GPL question
Whenever I push the car through a corner and effectively do a very low angle powerslide, I get this oscillation from left to right. Does anyone know how of fix this problem. I'll be steady - that is no drifing across the track either left or right, but the oscillation will continue right through the turn. Any ideas? |

This sounds like a problem with your force feedback. I'd recommend reducing the latency to near zero (0.0005) or zero in the core.ini and/ or reducing the force acting on the wheel by increasing the torque number. I use brr's FF patch http://srmz.net/index.php?showtopic=4226 where it's recommended to put damping to zero. |

Same here. But, generally speaking, increasing rebound damping should help that. Stiffening front and rear roll bars might also help. Pat Dotson |

I'll try turning them to zero. However, it only happens when you hear tire squeal of course - just to clarify. |

More damping will reduce the amount of oscillation as spring loads change. -- Pat Dotson |

However at a first test with a BRM and a Cooper, I'm still getting the oscillation, although it *might be less - that is requiring a harder drive to cause it to happen. I'll have to experiment with Monza I guess. The first turn there is the one where I first noticed it - with the Lotus. I'll have to try raising the damping a lot higher to find out I think. I've used the recomendations in GRE, but they didn't seem to stop it. |
