    Hello everyone,
    I don´t know if I´m the only one, but since last 1.6.7 update I´m having stutters in every race, no matters number of cars, track or day time. Before 1.6.7 the game was completely smooth running almost everything in high settings, and even after lowering graphics & performance settings as texture quality, track reflections and more the issue persist.
    I have a fine-tuned Windows version optimized for gaming that´s completely up to date as well my graphics card driver, therefore I don´t thik that can be the reason. And as I said before, the game was running completely smooth before the update.
    Restoring game files in Steam and deleting my AMS 2 folder in my documents also didn´t solve anything.
    I´m stuck at the point I don´t know what else I can do.
    Any help would be much appreciated, thanks!

    Hello,

    Sorry you read you're experiencing issues. Can you try the following? Navigate to AMS2, then right-click and select Properties. In the launch options, add -pthreads 2 to the command line. And see if that solves your issue.

    Thank you,
    Marius

    Hi Marius, stutters are gone but not competely. They only happen when dusk time comes. Is that normal? I think my system is enough powerful to ride them… Thanks

    That's already something positive. Uhmm, only I could think of currently is disabling UDP, Turn LOD in graphics to off, and pit crew to player only. You can also fiddle a bit with the visuals in the other 'graphics'-tab.

    Try turning particles down to lower levels and see if it helps ..

    Thanks very much for your tips Marius an the quick answers.
    All of these options were already disabled and in my graphics tab everything is switched to medium, motion blur is off and rendered frames in advance to 1.
    Did the game after this last update become more demanding? I don’t know how can I run everithing at high settings before an now even lowering everything I still having stutters…
    Also I have to say I can run LMU which is way more demanding at high graphics settings and runs smooth, that’s why I think is something related to this last update.

    If I recall LOD was the only graphical addition that could be classified as making the game more demanding. However, you can switch that off in the settings.

    Check your graphical drivers as well, etc. Perhaps you updated something that doesn't play nicely with AMS2. Every computer and OS is different, which means a lot of variables that can cause issues.

    I've found dawn/dusk transitions to be pretty tough on hardware, depending on the circuit you select. At Jerez 88, simply looking in the same direction as turn 4 can make my avg fps dip from 120+ down into the mid-30s. Take the same turn one hour earlier/later on the game clock and you get a deadlocked 120Hz with lots of GPU headroom to spare. I've tested it with an empty circuit and w/48 AI opponents and it's exactly the same either way. It is a bit of a bummer as those day/night transitions can be breathtakingly beautiful (especially if you have been running in a long stint in the darkness and sunrise washes over the track in the early morning).
