I thought this was always a anomaly meaning you just can't replicate it verbatim.
I suffered this like I said in news thread with every wheel I had through Black Momo to CSW , actually can't recall CSL DD I have to test when I get pedals back.
Never busted a plastic Momo till rF2 lol ( wrecked about 6 in a year 60+hours a week, all replaced under warranty ) awesome immersion for a crude wheel and pedals I could feel every little slide and lockup.
Anyhow FFB loss I had 300+ driving F3 ( lower stress car) in my room F3-Rookies.
I would say maybe 1 in 10 ever mentioned this problem.
There was no pre-requisite it just happened in different situations.
Long session, fading FFB, sudden violent steering wheel inputs, spiking, high impact collisions, just sitting in pits.
Seems to me it's a mix of things. rF2 has this aversion to slowing to a crawl when you do certain things with a lot of content. Make a big rfmod with say 40 tracks and all GT3. Now when you click install in MAS2 or refresh Mod Manager and click there it is instant.
Now trying uninstalling it in either mod manager or Mas2 and it will choke.
Same happens with swapping big series in game. It is like it is running the same info checks every time that it should be keeping in cache.
Another example is go and try resaving/updating a replay 4-6 hours + Then try loading it again you can go and have lunch while you wait, again like it is analyzing reading I don't know all this replay info again before it can load.
Another instance is the longer room is up the slower it is shutting down.
I have Master X570 and 32GB samsung b die and 980Pro for rFactor2.
Every other sim runs as you would expect in all the above situations.
P.S. Biggest difference I saw was through lowering FFB , smooth steering, don't hit anything lol
