I have had it for 6+ years now and it has devolved some problems. On professional or higher it shakes back and forth to where I halve to hold it very tightly so that it stays centered. My second problem is that it losses its center point and thinks its center is about 15-25 degrees off center.
At least I know I have 2 more years with my wheel LOL. Thankfully I haven't had an issue yet. I can't afford to buy a new wheel and refuse to go back to the DS3 for gt5.
Seems more like a GT5 feature to me then issue with your wheel, force feedback can be strong and shake in the wheel is implemented. Try lower feedback?
That could be more of an issue, but seems to exist in all Logitec products from what I got. I do not have this.
However, pull out, plug in = recalibration and solved? or not?
