Even the fastest available CPUs struggle to keep flagship GPUs fully utilized when chasing 200+ FPS in titles like Valorant and CS2. At 4K in AAA games GPUs shine, but competitive titles expose CPU limits regardless of resolution. The core argument is that GPU performance gains are outpacing CPU progress, meaning more GPU horsepower alone won't unlock the full potential of ultra-high refresh rate setups until CPUs catch up. ## Full article daily.dev links to this article rather than hosting it.
