Dialogues and cutscenes can cause a drop in performance to around 50%.

When playing NARUTO ULTIMATE NINJA 4, I can smoothly run it at 4K resolution. However, when there's a dialogue, the performance drops, and the characters start speaking in slow motion. This issue persists even at other resolutions, including native resolution. I'm using the 8-core GPU 8GB MacBook Air.
