I was testing out all the wheel settings individually with everything set to 0 and upping them one by one in order to better understand them. I had read the guide first so when I raised vibration to 100 and everything was at 0, I was surprised when the wheel did not vibrate at all. Not off jumps, slamming into a wall, or when the tires were losing traction. So I raised Forced Feedback Scale up to 100 and then there was the vibration in all the correct places. Everything else was at 0, so Vibration was isolated.
This contradicts the Wheel Guide, so it’s either a guide mistake or a mistake in the game programming.
