I have pretty much the same problem that occured with the 930. This time though i don't have slow motion but other player squeeze pass me as if i was stationary. It is easier to explain with a video, look in the mirror... https://www.youtube.com/watch?v=TxqkpCzj9bI sorry for the bad quality
I don't see the CPU bar in your video? Are you saying it's maxed out? You didn't turn the multithreading option back on did you?
Have you perhaps deactivated hardware plugins by accident? I had something similar if i did this. You can assign a key in controller settings
hardware plugins were activeted. btw i just tried with sim processor thresh = 3 and...the situation is now back as with the 930. I have slow motion with 25 ai but the game is playable because the bar is not always maxed out.
