(Caveat, I am on the pro, but it seems this is the same.)
It can be normal & seems to happen on high frequent strong-ish changes to the motor speed.
But 2 points:
- Currently there is an issue with the latest firmware(2020.3) that produces this(possibly not EXACTLY this sound here) where it would not normally occur & affects the FFB feeling on many units(mine included).
So, important to use firmware 2020.1 for now.
- With good firmware this can happen too & depends on your settings.
A combination of reconstruction filter at fast setting & high speed slew rate will make this happen more & at different settings depending on simulator’s FFB raw data.
It is NOT really bad in any way, but can point to using too raw data, that is not well formed before it hits the motor. Sometimes it is what you prefer though, it depends on your personal opinion on the feeling of the FFB.
I personally normally dial it out a little(but not completely by any means) by either using a slower recon filter or slower slew rate limit or both.
Disclaimer: I could very well be wrong on assuming it to be caused by high frequent strong-ish changes to the motor speed. Mika would know if I am way off.
Hope this helps, otherwise just disregard completely 8)
