Severe slow-motion / heavy gameplay and input delay during matches on PS5

I am experiencing a severe gameplay performance issue in FC 26 on PS5. During full matches, the gameplay becomes extremely slow and heavy, with delayed player movement, passing, turning, switching, and other controls. It sometimes happens from the beginning of a match and sometimes appears after playing for a short period.

The important part is that this is not normal online lag. I can reproduce the issue in offline Kick-Off with Wi-Fi completely turned off.

When the issue occurs:

Players move and respond in slow motion/heavily.

Passing, turning, switching players, and skill moves feel delayed.

The menus remain responsive and open normally.

Arena/Training mode can run perfectly smoothly.

I have tested:

PS5 version of FC 26

PS4 version of FC 26 on the same PS5

Offline Kick-Off with Wi-Fi completely disabled

A completely different TV and a completely different internet connection

Different FC 26 settings/visual settings

USB-connected controller

Other PS5 games, including RDR2, which run normally

The same problem continues despite these tests.

Because the issue occurs offline, on different displays/internet connections, and affects the actual match gameplay and replays while the menus remain normal, this appears to be a FC 26 gameplay/performance/frame-pacing or simulation issue rather than an internet connection problem.

Please investigate this issue on PS5, especially the difference between smooth Arena/Training gameplay and the slow-motion/heavy gameplay occurring during full matches.

Is this issue going to be resolved in FC 27, or should we give up hope of getting this fixed in FC 26?
