Playing with this mod collection i encountered some issues with cars like the McLaren Senna. Switching gears from 6 to 7th the gear ratios are unable to sustain the actual speed and the car start to slow down by 60/70 Km/h. This happens to some others cars/supercars at top gear, but i don't remember wich ones atm.
Someone has a fixed car database to share somewhere!? I play only offline.
The only occasion where i was able to use a proper trigger brake/accel and analog sticks with this game was when using a xbox360 controller on Windows.
On my Steam Deck (where i play this game mostly) had to play around with controller configurations quite alot, the game recognizes the analog sticks (they are not smooth by the way and tends to give cars a rough spin on corners), but with the triggers you have to manually set them as ANALOG in the Deck configuration and like the sticks, the area between the system detects an half pull to a full pull is somewhat short.
With my ps5 controller on SD is exactly the same, i don't have a x360 controller anymore.
