@Karsten Hvidberg I haven't tested anything yet ... I just loaded the file * 47 LOW, I launched the game and I tried two configurations ... the first time 50-50-70-5 ... and the second time 80-80 -70-5 ... I tell you on the confidence that this is a great file .... in both configurations I had a WOW effect on the GT3s at SPA ... In the first case a lighter and more informative feeling with a not very full center but still full ... and in the second case the feeling is of resistance, fullness in the center that overhangs the effects a little but they remain present .... I must say that in both cases I have a great feeling ... fantastic !!! Would you advise me whether to start from lower or median values (both Gain and LFB) or I start from high values for both? Or the median Gain and the high LFB ??? For how the file is conceived, in order to cover a wider range of cars what do you recommend??? Always Low Gain possible and the conseguence LFB for full center??
