PC Stutter and Input Delay in Ultimate Team Since Launch

I have been experiencing severe performance instability in EA FC 25 on PC since the game launched. These problems happen randomly: sometimes the game runs perfectly for hours, and other times it becomes unplayable immediately when opening Ultimate Team. There is no consistency at all. The main issues are: 1) Heavy stutter in Ultimate Team menus and in matches, especially when entering UT for the first time after launching the game. 2) Gameplay becoming completely unstable: freezing, stutter, delay in defending, and inconsistent responsiveness. 3) GPU usage randomly jumps to 100% even on menus, while at other times it stays low and the game runs perfectly. 4) Sometimes I need to restart the game 3–5 times until it randomly decides to work properly. 5) There is no clear pattern: some sessions run smoothly, others are full of stutter and delay for no reason. These issues started long before I got my new external monitor, so the monitor is not the cause. My hardware is more than capable of running the game, and every other game I own works perfectly with zero problems. I have tested every recommended fix: driver reinstall, EA App repair, DirectX toggles, config resets, clean boot, monitoring temperatures, clearing cache, adjusting settings, etc. Nothing solves the randomness. I am still having these problems even after the most recent updates (14–17 November). Many other players have also reported random stutter, defending delay and GPU spikes, so this appears to be a widespread problem and not hardware related. I paid for early access and was not able to enjoy it properly because the game performance has been unstable since day one. I am requesting that EA investigates and fixes these performance inconsistencies in Ultimate Team on PC, because the game experience is being heavily affected and the issues persist across multiple updates.
