I have a Fanatec CSW 2.5 with driver 328 and I had 90 fps then I upgraded to a newer firmare and I began to have a fps dropping that makes the sim not playable any more .... I made many tests yesterday and always happened the same: - I start the game and at the beginning I do have 90 fps - then after about 2 minutes (second lap) they begin to drop to around 50-70 - after about 3-4 minutes they drop to around 20 and if I try to continue, they continue to drop to 2 ! .... It's very strange because even if I exit from the race and go back to the menu and then again I start a new race, the fps do not change from the level they reached before, I mean they stay at the lower I had before and from there they go go lower when I start to drive ... Only if I exit the sim and restart it, than I restart with 90 fps ... when I tried reducing the FFB to 180hz (from default 360hz) I can make more time driving before the drop begin ... so I went back to 328, but I would like to use newer driver for AMS2 please help me
