Keyboard disconnecting in matches and heavy stuttering (after update)

I paid for Battlefield 6 and played without issues during the first months.

Now the game doesn't just glitch - keyboard input randomly stops working during matches, severe stutters appear, and my CPU starts overheating.

My laptop is powerful, and other modern games run at high settings without any overheating or performance issues.

It feels like optimization has been broken. Updates are released, but core technical problems remain unresolved.

I paid for a game, not a hardware stress test. If a product is sold for full price, it should be technically stable.
