Same here, although im not using an Elite controller, I am using an Xbox One controller nonetheless. At least until I can find a joystick/throttle or yoke combo that suits my needs.
It seems to be an issue with the analog module itself. I identified this not just in FS2020 but in a lot of other games. More recently, in Forza 7 as its the primary game i play on PC using a controller. Its impossible to drive straight, on a track that has a straight-away such as the Circuit de la Sarthe or on the Nurburgring
To be honest, this is a common thing to happen with analog sticks as overtime they lose their deadzone and sensitivity and no amount of calibration will help because increasing the deadzone itself I’ve found only exacerbates the drift.
Previously I used to simply replace my controllers because, at the time, PS2 and PS3 controllers were typically $20-30 bucks a piece or less, so they’re cheap enough that replacing them was a non-issue. Plus I didn’t know how to simply replace the analog device with a replacement because i had zero soldering skills at the time - so theres that.
Opening the controller and cleaning it out with generous amounts of high % of isopropyl alcohol and some compressed air MAY correct the issue so you could give that a shot, but it didn’t work for me.
In the past year, I’ve finally gotten into the hobby of modifying and repairing game consoles and controllers so I have decent experience with soldering, so it doesn’t take but buying a lot of analog module kit. They vary in price depending on what else is included but on average you can spend $10 with shipping for a set of 4 to 6 analog modules and repair any controller. A better deal than spending $50+ for a brand new controller.
I’ve plugged in my PS4 controller and I don’t have this drift issue. And I do have another brand new Xbox controller that Amazon sent by mistake when I ordered only 1 Xbox One controller on impulse because it was in a color combo I really liked - so its not like I don’t have backup controllers.
At this point i’m just biding my time using a controller because as I’m not going to be taking my time with FS2020 until I can:
1)Locate a throttle/joystick or yoke setup that I want to settle on, as there’s so many and I’m only halfway through the list of the ones I am leaning towards - reading their reviews and searching for any known complaints or issues to narrow down the best ones.
2)Biding my time until GPU board partners like EVGA and ASUS make their nvidia 3000 series GPU’s available as my 980Ti is showing its age.
