Severe input lag only in RUSH mode on PC (EA App)

Hello,
I'm experiencing severe input lag exclusively in RUSH mode on FC 26 for PC, purchased and played via the EA App.

All other online modes (Division Rivals, Squad Battles, Pro Clubs, etc.) run smoothly and are fully responsive. However, in RUSH mode, the delay between input and on-screen response is so extreme that the game becomes unplayable.

I have already tried the following troubleshooting steps, with no improvement:

• V-Sync disabled
• Borderless window mode enabled
• FPS capped at 60
• EA App overlay disabled
• Windows Game Mode and Xbox Game Bar disabled
• Cross-play disabled
• Launched the game directly from FC26.exe
• Tested both controller and keyboard input

I also enabled the network performance overlay during RUSH matches, and all values are stable:

• Low and stable ping
• 0% packet loss
• No jitter

This confirms that the issue is not network-related, but rather a bug or performance issue specific to RUSH mode on PC.
