FM24 Match graphics is running jagging

Have you tried without the graphics installed - does it make a difference to performance as the amount of additional files can have a strain. 

Would recommend removing your cache and preferences folders too:

Do you have a lot of leagues running at once? This happened to me in FM23 in my last save where all of my matches stuttered during play, and it was really difficult to watch. It wasn't the GPU that was the problem - it was the processor (I'm using a Ryzen 5800X, 32GB RAM, and an AMD RX6900XT GPU). I'd just wait until my processor fan died down before clicking on the 'Tactical Meeting' button to start my match, and it'd run smoothly after that because the background matches had already been processed. I thought I could load a lot of leagues at once with those specs, but it didn't turn out that way tbh.

Probably the best way to test is wait about ten minutes before clicking 'Tactical Meeting' and seeing if your match experience is suddenly smoother, or just do a quickstart save with one league loaded and test a friendly match with it.
