PS5-FC25 Slow and Unresponsive gameplay when connected to EA servers

No. EA don't know what to do about it, so they refuse to acknowledge the problem. They did reply to reports of stuttering on PC back in November, but that's still an outstanding ticket. They don't deal with technical debt. They just push new cards & features. Eventually, the game will be literally unplayable, and they'll have years of work on their hands.
