I use a DD Pro with Fanatec recommended settings.
Only ever encountered wheel shaking when on secret route X going 350mph with the tomahawk. It was definitely uncomfortable, but unless there's a hidden audience who loves to go at that sort of speed, where else was shaking occurring? (also I noticed that if I leaned forward and braced my elbows against my legs, the shaking would disappear entirely, I could control it easily with one hand. So was it a feedback loop issue of amplifying tiny movements, I wonder? And since the change affected both Thrustmaster and Fanatec wheels, I'm inclined to think this is entirely on PD's end rather than the wheel manufacturers)
This feels like a massive overreaction to a tiny issue. A bit like when that one Pokémon episode aired and caused seizures, the episode was not only pulled from rebroadcast, but for decades afterwards many anime studios sharply dimmed all scenes with any amount of bright moving effects (don't know if they still do, I've since dropped off anime watching, but it was there in the first few seasons of My Hero Academia). It was really awful, made me think my TV was broken at first.
Fingers crossed they revert this, ugh.
