freezing and sound issues

everylap the sim pauses then fast forwards. Also doesn't respong to commands like changes in fuel when it happens.

Also when closing browser (Edge on Win10) the sounds of the sim continue in the background unless I close ALL my browser windows

Yes, we had it in Singapore and few days ago in Monza, the game freezing 2-3 times every lap the whole race.

This time round in Singapore, I changed my strategy. To be sure i shanged it in settings at the top and as it doesn't change along right away in the bottom of the screen (still), also down there. I ended up with the fuel that was set originally. Same seemed to happen for Simon.

I did notice that the lap estimate for the driver that didnt get his fuel right, appeared to be wrong in the settings menu for the first 2 stints. Basically what it usually says at the start of the race when the guestimate is somewhere around 80ish.
