The sim has been missing vibration since the second patch update. I use an X-Rock gaming chair with speaker and vibration, I really loved how the chair would vibrate when the engine is running wildly. It would be nice to have some vibration back in the sim.
They actually added a new, or more pronounced, vibration effect when the engine is running at low revs. The aircraft body visibly shudders, and you can see the magnetic compass bouncing about.
I’ve never used one of those chairs before, but I found the following on their website:
WHAT IS THE TECHNOLOGY USED TO CREATE THE VIBRATION FEATURE (ON VARIOUS MODELS)?
Unlike a rumble-pack that is commonly found in game system controllers, the X-Rocker’s vibration feature is the result of combining volume, bass and a vibratory mechanism.
So what is the vibration component actually driven by? If it’s audio, and a particular frequency range, that visible jiggling in the sim is just a visible effect. The pitch of the engine has probably not changed, just the UI effect, so it may not make any difference to the the way the X-Rock expresses this.
