Pro Clubs Drop-In — Severe Input Delay & Slowdown

When playing Pro Clubs Drop-In, the game slows down dramatically and produces approximately 4–6 seconds of input lag. Everything I do is delayed — passing, shooting, movement — and the match clock runs behind other players in the same game.

What works fine:

• All menus and UI
• Cutscenes and replays
• All other game modes (Career, Kick Off, etc.)
• Drop-In games with fewer players

What I have already tried:

• Lowering all graphics settings (including Strand Based Hair, Shadows, Ambient Occlusion)
• Locking config files to prevent settings from resetting
• Closing all background applications and browser tabs
• Using a cooling pad
• Updating GPU drivers
• Playing on a wired PS4 controller
• NVIDIA Control Panel optimisations
• Disabling Hardware-Accelerated GPU Scheduling

None of the above made any difference. The issue occurs consistently only in Drop-In when the lobby is full.

please help..

Here is what it looks like:
