Is not that easy…
The most annoying problem is related to wireless wheels disconnecting ingame, so if you dont have any, you may have Stable version with 2020.4
If you have any wireless wheel, then It is solved after 2021.x versions, buuut you can clearly see that 2021 versions aren’t stable for all
2021.8 has some extra noise not only during idle as release notes suggest but also during under torque operations.
2021.7 is smoother in that regard. Ref
Hopefully it’s just missing adaptive current measurement and not something else USB related that happened after 2020.10 when for a few releases we had some grainy feeling that required extra Recon filter.
it was Ams1, not sure if it was related to the sim or not. with 21.8 it happened in Ac and rf2, so it seems to happen randomly. ffb is fine, same as you.
We think its due to the “default” current measurement algorithms in this release. We have a servo drive fw build ready with better ones enabled, but of course need to test it first. It makes sense to build a good release, as many other things are ready as well:
importing of classic profiles to the paddock without working with ini files
upcoming “quick try” functionality for paddock
some hw support things related to battling with global chip shortage
You can review release notes for all releases after yours to see if you benefit from any of the changes there.
I’d say from my ignorant outsider view until 2020.10 we had mostly useful fixes, things took more on experimental side since then with some core internal changes cascading in bugs that had to be fixed afterwards. 2021.7 had pretty much most gremlins worked out, or we can wait for the next patch Mika promised, seems like 2021.8 even with all the fixes is not that great due to the noise.
