10.15.6 causes FPS drop in team fights

Hello,

Since upgrading to 10.15.6 on my macbook pro, i have been getting some bad lag spikes. The game runs well until there is a team fight or a lot of map animation and then it is unplayable. It seems like I experienced this upgrading to 10.15.5 as well and it eventually went away (last couple weeks the game ran perfectly).

Would appreciate someone looking into this or some advice on how to mitigate.

Thanks!
