    Nurburgring Nordshleiffe (btw, length is 20 Km, not 25, that's been wromg for years now)
    Ferrari 488
    Rain, but similar on dry track.
    After a minute race, engine loses power and cannot accelerate.
    Then it recovers slightly, but too late to catch up.
    No settings changed.
    It doesn't happen to AI drivers.
    I can't race anymore.

    Can you post a video of it happening.

    Do you log via Motec? Just wondering if your throttle is working reliably (video overlay of replay would show this too…)

    Thanks for your responses, nice to see someone listens!
    No logging via Motec.
    Steam rFactor2. High end computer (this wasn't happening before 5th Feb 2022 anyway)
    Default settings Ferrari 488 at Nurburgring-Nordschleife
    Here's the video, with engine not accelerating more at 50 seconds (4th and 5th gears)
    I made a video (zipped mp4, 19MB), but the page says security issue, refresh and try again (several times).
    In the video you see the car losing acceleration at 4th gear, and not accelerating anymore at 5th gear.
    I'm sure you'll start getting massive bug reports from other players soon, this is a game breaking issue.

    It feels like the gear ratio is too high and the engine cannot keep up.
    The gear settings are the default and they were OK the day before.
    Rain conditions, but also noticeable on dry track.

    Is it the S397 488?
    And if yes, which one, the GTE or the GT3?

    You should upload the video to youtube, I don't think you're allowed to upload videos here.

    It's the S397 first rFactor Ferrari 488 GTE.
    Video uploaded to Youtube:

    At 00:50, in 4th gear, acceleration becomes lower, then in 5th it just doesn't go up at all and the cars ahead go away.
    Then I stop the car and get out of the race.
    I tried several times, rain and dry, always the same problem.
    Before yesterday, I used to be equal or faster than AI at that point of the track.

    I've noticed other random misbehaviours in rain, but not consistent enough to reproduce again.
    Reducing from 5th to 4th at a later point in the track while braking, the engine got revved up as if i had shifted down to the 1st gear.
    There is no way, in real physics, that braking hard on wet ground and shifting down just one gear, the engine goes over the RPM limit.
    I think it's not just this car, something more general has changed in the program.
    I'll post other findings when I have more feedback.

    I'm testing now, fifth gear is a little long, but it still accelerates, and the rpm still climbs.

    I also have tested it and didn't notice the Problems that you have described.
    I only tested in dry Conditions, because i live in a Town where we have enough Rain in real Life. :D
    The only Thing that is a bit strange, is when you are on full Throttle at 6th Gear (Indy Oval), the Engine Sound sometimes goes down, as if you immediately loose 300 Rpm.
    But that could also be caused by the Sound File.
    BTW, when you race on the Indy Oval, do you have the same Problem there?

    Thanks for looking at this!
    I'll check the Indy Oval.
    The day before I had this problem, the F488 GTE was able to gain rpm even in 6th gear (1:1).
    Maybe some transmission ratios have changed?
    Or maybe I have changed settings inadvertently, while exploring the new UI, it's hard to tell.
    In that case, I haven't found a clickable link where to reset to defaults (i see a <default settings> label anyway).

    Maybe i misunderstood you, but you can set the Setup to default, on the left of the main Setup Page under MANAGE SETUPS (the red marked one).

    I watched your video and it looks like your brake pedal is binding a little. See the red bar go up 3% at the place you reported problem with.
    You can add a little deadzone in the config menus. If it gets worse you might need to clean your pedal pots.

    Problem sorted after resetting the car to factory defaults.
    I hadn't changed anything before, or maybe I did accidentally, when the new UI came in.
    So it's not a game breaking issue, as I said at the beginning of the thread, although there are some occasional strange behaviours on wet tracks.
    Thank you all for helping me out with this, I really appreciate your advice. Back on track.

    This continues to happen randomly. It may be related to the UI bug reported where the gear ratios cannot be adjusted properly. In my case there is no ratio adjustment at all.
    I can confirm this also affects other cars and weather settings.
    In certain sectors of the track, the car loses power.

    I think you misunderstood.

    Your brake has an issue. You either need to add a fair bit of deadzone or clean the pot (potentiometer), or replace the pot, or consider hall sensor instead (as a mod to your pedals, or a new set of pedals).

    This isn't a game issue.

    *Judging by another of your posts I think you have the CSL pedals, so that should mean hall sensors. You'll need to work out what's going on there - lack of clearance, flex, something loose, or a lazy left foot is making your brake drag.

    An accurate inputs display tool is very handy for this type of thing - dxtweak2 or the like. Often the game and manufacturer software make small inputs hard to spot.

    Typical Fanatec issue... Their sensors are troublesome to say the least. It's more of an exception to not use a little bit of deadzone.
    (previous Clubsport pedals V1 and V2 victim)

    Lazza's analysis must be on the right clue.
    CSL pedals show erratic unstable values with noisy quick variations. Looking into that.
