@ajmcspursfan you're getting views from the full player spectrum here 👌
I don't have much to add, my birds all sing to the same tune. I used to play on a pad back on PS4 and made it to no assists other than ABS on medium back on F1 2019 or 2020, don't remember. On the following title, grip felt much better and I turned off ABS too. This year I got a PS5 and playing with the adaptative triggers made it even more of a joy: having more fun and feeling even more in control. When F1 22 was released, I had already upgraded to a budget wheel (Logitech G923), but still spent some good hours playing with a controller.
A wheel does make it better, but I genuinely think that the triggers on the PS5 still makes throttle application easier.
You've got two great suggestions here, short shifting and throttle linearity.
Short shifting is what Duck is referring to and it helps. Automatic gears was the first assist I turned off back in the day so don't take my word for it, but I think you can still manually upshift even with the assist on? You don't have to do this all the time, mostly on slow corners. Get in wide, brake, turn in and, as the game ceases downshifting it for you, just go about upshifting even before opening up the throttle again. I got cozy with this year's traction relatively quickly, but it definitely has a narrower "safety" window for throttle. It is easy to go overboard and lose the rear. Short shifting will help you a great deal if you can – and it is not at all a workaround; the technique will still see plenty of application if you ever decide to go with manual transmission in the feature and it is way more prevalent in the real sport than a good chunk of the player base believes.
Now throttle linearity that Toto refers to is even more immediately applicable. Just fire up the settings and dial it waaay up, just as he said. It will basically change the throttle application vs button input scale. So if you press the R2 for like 50% of button travel, instead of the game reading that as you opening up the throttle to 50% it will translate to 30%. The difference between 80-100% trigger input will be swift, but at that point you're probably safe to smash the throttle anyway so it is all good.
Pay attention to the calibration screen. On the right you'll see a button prompt to get into a test button mode, and the game will display just how much input it is reading for whatever you're doing with the pad. Set it up so that you can easily and consistently hit around 10-20%, 25-33%, 50% and 80% pedal input and you're good to go.
Edit: good visualization of throttle application, even though it's from a different game.
