Certain dial racing games feel very unresponsive to me almost as if there is a deadzone on the wheel. If you spin slowly, nothing happens but once you hit a certain speed it will start responding. I thought that might just be how they were originally programmed but I've noticed that the inputs also respond differently in the MAME menus.
Two examples are Wheels Runner and Rough Racer. Below is a screenshot of the Dial slider under analog controls in Super Sprint. I can move up and down easily along this bar and when I stop moving it remains there. I cannot get the Dial bar to do this in wheelrun or roughrac. If I spin hard, it will slightly move away from the left edge but immediately return to the edge. I tried Rough Racer on 0.161 and even though the bar isn't in the MAME menu, I can tell within the games test menu that it's much more responsive no matter how low I set sensitivity. It's noticeably better during gameplay.
I have a MAME Testers report on wheelrun but am now thinking that the issue is more widespread. I have a comparison video in that report. I'm curious if anyone has any input or guidance on this.
