Your video looks pretty good. That would be the benefit of a native wheel I suppose. I guess you are showing this because of the notch or click sound we're hearing. I don't think that is unique to GT7 but in fact to the wheelbase itself. It has been discussed quite a bit on the Fanatec forum. I'm sure you're probably aware.
I've installed the latest Drivehub firmware. Definitely a noticeable improvement. I still see some slight stuttering and it doesn't even have to be a busy car corner, just be busy scenery trying to flow thru. I was able to calm it down quite a bit by changing to "race info only" in display settings. I imagine this will smooth out over time with more Drivehub and GT7 updates. Maybe even some PS5 updates that could potentially turn up some performance on the machine itself. All in all I'm pretty happy where it's at for now. Happy racing.
