Simucube 2 pro randomly grainy feeling

Hello guys, since last 3 days when I drive on iracing, my simucube 2 pro, feels grainy randomly for few seconds and back to normal. It’s just like lose recon filter for couple of seconds and it feels like when I turn the wheel I’m just tur a gear with spikes. I’ve tried multiple solutions:unistall true drive, reinstall, upgrade version, upgrade firmware, delete all profiles, create new ones, increase recon filter, delete config.ini in iracing.Nothing changes.

Someone can help me?

Maybe it is vibrations from the track that can now be detected as the FFB is 360Hz instead of 60 Hz.

One corner I have this is at the exit of Adenauer Forst shicane and the straight just after it.

Nope bcs I have 360hz from the start, and this feeling I have it’s about 2-3 days ago without changing nothing in the true drive. Suddenly it starts feeling grainy for few seconds and back to normal.

And it’s not in particular part of the track, but randomly in various corner and next lap maybe I don’t feel it in that corner.

Is there a difference if you run with 360 Hz vs 60 Hz FFB?
