The Frostbite engine has CPU cache latency and RAM memory latency bottleneck issues. That's why the game's FPS doesn't increase with core count, but does increase with newer CPU architectures with larger CPU caches and higher IPC (instructions per cycle).
I'd argue if Frostbite were well optimized it would be able to use the extra cores to increase the FPS. The graph below shows more cores don't help increase FPS. Only around 3fps difference between a i5-12600K and i9-12900k.
The only way to increase FPS with Frostbite is upgrading to newer CPU architectures which minimize the cache and memory latency bottlenecks.
Posting a video, concluding things, that are not in the video. Classic Stewy. Must be hard to see your game dying. You might realize it some day.
Edit: For everyone that doesn't want to believe: Just watch the Nvidia promo. Constant stuttering and FPS-drops. (Attention: Stewy will decline that, as he will say GPU doesn't matter. I guess, Nvidia is running their high-end graphic cards with deep knowledge on potatos instead of high-end hardware.)
