> you can't tell the difference with 150 FPS and 165 FPS First byte latency makes cache misses significantly slower which in turn makes 99%ile latency (which is perceived as microstutter by humans) significantly higher even if it doesn't affect throughput (fps). This was well documented way back when the first DDR5 sticks came out and they performed like crap compared to overclocked B-Die DDR4.
