Yes - I agree with what others have said . Although I am using Grid 2019 , issue seems the same . Like digital stammering - like you are trying to play a cd with lots of scratches. Forum on steam suggests to change the bitrate on sounds settings -> additional settings -> advanced . This has not worked for me . Generally , sound is bearable on a qualifying lap with just myself on track . But add in the other cars and it soon deteriorates . It may be to do with the mixing of sounds .
