HI all at RD, I have a problem which I have posted over at AC forums but I wonder if anyone has had anything similar and perhaps could shed some light on my problem listed below: Hi, I have a problem and hope I posted this in the right thread. Basically everytime I start a race I get a very noticeable stutter that really spoils my enjoyment with Assetto Corsa. For some unknown reason, I don't get any stutter in practice. I have tried the very lowest settings, Tried capping my fps to match my monitor 60hz, Tried with-out my wheel and with a xbox controller, Tried all known suggestions as well, I have even tried disabling my wireless adapter and it seems nothing stops the stuttering. I could cope if it were a minor stutter here and there, But this happens at crucial points, like the hairpin at imola, Right in the braking zone. I am so frustrated as I love this sim, But I am at breaking point. I doubt if AC is to blame but on the other hand my system works flawlessly with other games. If there is any suggestions as to my problem please post as I am desperate to get this running without this stuttering. Many thanks in advance, Terry.
