>>11820568 (OP)>How do you get smooth controls when emulating arcade racing games that relied on a steering wheel if all you've got is a controller?You can't.
A controller stick doesn't have enough range of motion for smooth driving in racing games that you want. It's just a tiny stick after all. Even if you make adjustments to deadzone and all the other settings, your car will still be twitchy when moving the stick.
You absolutely NEED a steering wheel for the the super smooth you are looking for. Believe me I've tried with numerous controllers and settings. I gave up. Then I went out and bought a cheap used Xbox 360 steering wheel for $25 from my local Goodwill. Cleaned it up, and connected it to my computer.
Problem instantly solved. I had super smooth motion when turning.
