split screen extreme laggy

Our kids got F1 2023 for XBOX Series X at Christmas. We've tried to get split-screen many times, but it is so laggy, jittery, juddering, that it is as good unplayable. This is on the most current and high spec Xbox console on the market! Is there a fix please EA?

Hello, I am having the same lagging during split screen (probably caused by smoke) on my Xbox Series X. There was another update a few weeks ago, but we still dont have solution for this...

The fix is to do a one shot qualifying before the race and all lag disappears.

F1 23 split screen lag - why is this still not fixed?

the workaround is to do a one shot qualifying before the race and all lag disappears -  but why is this not corrected via a patch? 

if you wonder why the sales are tanking, it’s because of issues like this being ignored.
