Series X, FH3 has started to run worse than earlier

As in title, any reason why FH3 runs now muck more worse than it did earlier? Has there been something in
console’s firmware-patches etc which could explain this? Game now runs visibly worse, it has some stutter
all the time and in general feel not so good as it were.

Only one who has noticed this? And other Forzas seem to run just fine(FH1/2/4/5 and FM5/6/7).

I get a lot of stuttering too in the game, I am on pc.The game used to run ok, but for weeks it has run bad, even if I lower the graphical settings.

Same issue on PC as of about two months ago. It’s an Apple-style move to get everyone to buy the latest stuff. Not going to happen for me. I can continue painting at 72 fps average with racing dropping as low as 64. Where as, before this, I used to average 120 fps regularly. Weasely practices, smh.
