    Basically the game suddenly slows down to 30fps from the usual 60fps after driving for a few laps around what ever track I'm on even with no opponents around.

    I've tried slightly lowering the graphics settings and changing the FFB to 180hz, still remains. Not exactly sure what's causing this.

    Here's my specs:
    Intel Core i7-4790 3.60GHz
    8GB Ram
    Nvidia GeForce GTX 760

    Most likely you're running VSYNC which will TRY to get a perfect 60fps, but will drop to half of this if your system isn't capable of maintaining 60. So instead of 58 you get 30 and instead of 29 you get 15.

    Try turning off VSYNC (if you don't override this in the Nvidia settings you can set it in the Automobilista config utility where you set the resolution etc). Without VSYNC you also get less input lag and a better more responsive 'feel'.

    I'm having similar problems also
    however, it's different
    I cannot live without vsync
    without vsync, the game runs in slow motion and fps oscillates cause lag and tearing
    with vsync, everything is great
    however, in the first or second lap I have fps drop to 59,58,57
    mainly out of the garage
    it pisses very
    the problem just as I'm driving
    and if I leave the pits again in the same session, will not happen again
    I've tried lowering the graphics and still going
    I set a button also to open and close the HUD
    when I open it for the first time on the track, it's a locked
    sometimes it happens also with Limiter

    what am I doing wrong?
    not happen with the GSCE and my fps is good in ams, with everything in full my fps is about 150
    I believe it would not have problems in using vsync 60 and alone on the track

    Just turned off Vsync and it's all good now. I don't really mind the screen-tearing at all.

    Thanks.

    Have you tried using a Max framerate lock via display setting to try prevent the FPS fluctuation? Much better solution for tearing then VSync, which should really be avoided if at all possible.

    I have my FPS set from 120 to max unlocked this cured the tearing for me

    I tried to use max frame rate
    however, not smooth like vsync (also, i have tearing)
    I really don't know what to do

    what is the best value in the max frame rate?
    My monitor is 60hz (samsung, 19 ')
    however at 60fps is not good (tearing, lag ..)

    My old graphics card can just about manage 60fps, but it can dip when under heavy load. To prevent really bad stuttering, I use the following settings:

    Nvidia Control Panel > Manage 3D Settings > Program Settings > Automobilista > Vertical Sync: Adaptive

    Nvidia Profile Inspector > Vertical Sync: Force On
    Nvidia Profile Inspector > Vertical Sync Tear Control > Adaptive

    If the framerate drops below 60, the graphics card automatically stops trying to provide a synced 60fps (this is often what causes stuttering) and just does the best it can, which might be something in the 50s. When it can reach 60fps again without straining, it syncs automatically.
