F1 2015 plays very well with a wheel, though the force feedback isn't the greatest. It has native support for the Logitech G29 and G920, though the default settings need to be adjusted for the game to be playable.
First off, the steering angle needs to be set correctly. By default, it uses the full range of the wheel instead of the typical 360° for F1 cars. Secondly, the force feedback is much too strong, maxing out the motors of these wheels, making it so you don't feel much of anything about the car.
In either case, you can get a lot more out of your wheel and improve the experience greatly by adjusting a few settings. In this guide I will go over the best settings to use to get the best feel in game.
G HUB Settings
The default steering angle in F1 2015 uses the full rotation of your wheel, which is way too much for an F1 car. They typically have a maximum 360° rotation, meaning you can turn the wheel 180° to the left and 180° to the right. F1 2015 doesn't have a good way to set the steering angle in-game, so it's best to set it in G HUB instead.
Create a new profile for F1 2015 with the following settings:
F1 2015 Settings
In Settings > Customise Controls > Force Feedback Options:
Feedback Strength is the overall strength of the force feedback. Adjust this higher or lower depending on your preference. The actual forces are calculated by the other two settings.
Environmental Feedback is the force you feel from the track surface, kerbs and going off track.
Wheel Weight is the primary force you feel in the wheel, based on the tire grip.
There is a very annoying problem with the force feedback in this game. The collision effect, either colliding with the wall or another car, uses the full Feedback Strength value, instead of the Environmental Feedback value as you would expect. This means collisions are extremely noisy on these wheels.
I've lowered the Feedback Strength to the point where the main force feedback is lighter than I would like, but the collision effect is tolerable, though still far stronger than I would like.
In Settings > Customise Controls > Advanced Wheel Settings:
I raise the Steering Linearity to make the wheel less sensitive when it is centered. This is more up to personal preference, so you may want to adjust this to your liking.
F1 2015 doesn't have the greatest force feedback, especially compared to later entries in the series. The collisions being overly strong and noisy is a real problem on these wheels. I also don't care for the exaggerated lightening of the wheel on understeer. Later entries in the series would make this optional, which was a huge improvement.
