FFB decreases while driving!

[xedos6]

For 3 days the FFB performance has been decreasing continuously while driving. I start with 100%, after one lap it's around 40% and after 2 laps it's almost zero! No matter what car, no matter what track. At first I thought it was the Alternative FFB app, but even uninstalling it didn't solve the problem.Does anyone have an idea as to what this could be?

That sounds very much like an overheating issue. What wheelbase are you using?
