This is the message I’ve just sent them, I hope they take this issue as seriously as we do.
I have had this Mac since April, Football Manager tan absolutely perfectly on it for months, until I started noticing very slight jittering and lag during matches. I checked to see if there was an update, there was for the MacOS, so I updated to Ventura and it was much worse, the only solution I could find was the match engine was much smoother in Windowed Mode for some reason, however, that's not how I like to play the game.
I downloaded the FM23 demo to see if there was an improvement, there was, so I purchased the full game and it played fine, until a little while later I noticed the slight lag coming back. After some feedback from a Sports Interactive member on the forum I took the overlay off in Steam and put in the commands suggested and it improved, but about 2/3 into the matches, it really starts lagging terribly and slows down completely, then improves, then does the same again.
I've been a loyal customer since FM08 and have loved this game. One of the main reasons I paid such a large price for this MacBook Pro was because I asked many users and they ensured FM would run flawlessly on such a powerful machine, yet I'm having worse performance than I did with older FMs on a very modest laptop that I had at the time.
Please could you fix this issue as it's affecting my enjoyment massively and putting me off future games if this isn't going to be corrected.
Thanks
