    I'm not sure what has changed recently with the updates but my system seems to have a lot of stuttering happening lately. FPS has only dropped marginally but the stuttering makes it difficult to judge corners and seems to be more prevalent in cars with a full windscreen.
    As an example, the USF is effected much less than the Nissan GTR 2011.
    The stuttering seems to occur MORE when behind another car and EVEN MORE on corners (while behind cars) I'm not sure if the brake lights of the car in front are partly the cause???
    I haven't changed any of the settings on the PC or in game so I am puzzled as to why the dramatic drop in performance.

    My PC specs are listed in post #886.
    As I said, the FPS is only down a touch on previously noted rates but stuttering has increased substantially.

    Hope this feedback is of some use and apologize for the lack of hard data.

    Question to @Christopher Elliott : Has this FFB situation - sudden reversal of FFB - been acknowledge by the team?

    JimmyT, same issue here after the last couple of updates lots of stuttering behind AI.
    Tried adjusting all graphic settings to low and have plenty of FPS.
    Now gone back to DX9 and all perfect on full/high settings!

    PC Specs: i5 2500k @ 4.3ghz, 8gb ram, GTX1070 OC, Bodnar SS2, HE Pedals.

    I have also noticed that when you hit ripple strips or get 2 wheels off the edge the graphics stutter to some extent. Not sure if this is relevant??

    To add info on my specs
    I use Fanatec V2 wheel
    Fanatec V2 pedals

    Its fixable by choosing your wheel brand preset in the controls settings and then set the buttons/axis again, and save as whatever name you want for it. Worked for everyone so far with that weird FFB issue including me.

    Christoper Elliot is looking for someone to upload the old (bad) controller.JSON that have the bad FFB deadzone/steering issue in here so they can look at it: https://forum.studio-397.com/index.php?threads/messed-up-ffb-resolved.56433/#post-901448

    With regard to the stuttering, is there a thread somewhere that notes how to record the performance and then send a log file to someone for analysis? I thought I read it somewhere but can't remember where.:oops:

    I have noticed that when it's doing this the CPU is at 100+ and the AI are rubber banding. (Again, not sure if it's relevant)

    Intel Core i7 3770k @4,6ghz, 2400mhz Ram, Gforce GTX 1070, resolution 5040x1050, multiview on
    Portugal, Corvette C6 Gt2, 29 car, starting grid at the end, 55fps, GPU load 50%, CPU limit.
    Portugal, Nissan GTR GT500, same procedure 55fps, but 95-99% GPU load.
    Its really strange that some cars generates such high GPU loads compared to others

    Here some results of other cars.

    Nissan GTR GT1 60%
    Camaro GT3 80%
    Indycar 90%

    I think the differences are to great, and lots of optimisation is necessary because there is nearly no headroom for night or wet weather racing with some cars

    Yep there is a lot of difference between the cars FPS wise. Also night is impossible for me personally. Shadows on LOW and daytime with clouds is ok. Smooth and nice. Night time it drops under 60FPS when the lights come on.

    I also tested turning shadows to "medium" since performance has gone up a good bit but it was too taxing. Not as bad as before, i think, but it drops FPS when just 1 AI car is near me (in my view).

    S397 has managed to get the performance up more and more so maybe they will be able to do a little more regarding night (lights) and shadows.

    Does F12 steam screenshots work for anyone? Maybe its triple screen issue? Anyone with triples that can use steam F12 screenshot? For me it hasnt worked since DX11 i think.

    some of my favourite tweaks which may help reduce PC resource night time
    -from my VR optimisations thread but applies to monitor users too :



    locate -if your rfactor2 is not on "C" drive then swap the "C" at beginning with relevant drive lett:
    C:\Program Files (x86)\Steam\steamapps\common\rFactor 2\UserData\player\player.Json

    open the player.Json file (use notepad), then search for as below

    Rear view mirror render distance
    search for "Rearview_Back_Clip " the number is the render distance in meters ( 0 is no limit )
    (I have this set to 30mtrs)

    Lowering details of cars in garage
    search for "Garage Detail" , set it to 0.01

    Reducing number of headlight in effect
    search for " "Max Headlights":256, "
    I have this set to 20 (change 256 to 20) plenty enough and saves fps

    Using DX9 i could´t notice any differences changing max headlights, even to 0, because this command didn´t change anything and i saw the headlights of all cars.

    I'll test in dx11

    I once had a PC running 4 way crossfire with each card having true 8 lanes@ 2.0
    I did a lot of testing to find out that the pcie bandwith was the main bottleneck

    unfortunately I dont have any more details but at least it confirms your story
