Game unplayable after second half - severe stuttering and input delay

After the latest update, nothing has changed — the game is still completely unplayable. I have followed every single recommendation from your official support pages multiple times. My PC is more than capable of running FC 26 smoothly (NVIDIA GTX 1650, updated drivers, stable internet, Windows fully optimized).

The only way the game works somewhat normally is with vertical sync set to 50%. However, every single match becomes unplayable in the second half — the game starts stuttering badly, input delay on the controller becomes extreme, and I have to restart the game. It happens every time, regardless of settings.

I’ve cleaned caches, updated drivers, set high-performance GPU, disabled overlays, and followed every step suggested. Nothing helps. I spent money on the game and FC Points, but because it’s unplayable, I feel like I’ve been robbed by this company.
