Overwatch 2 Getting 600 FPS Upgrade

NVIDIA and Blizzard announce that the maximum framerate of upcoming shooter sequel Overwatch 2 is being bumped from 400 fps to 600 fps. This is because the horsepower of the newly announced RTX 40-series will offer significant performance improvements. This is probably amusing to PC gamers who've enjoyed the hobby since the arguments over whether the human eye can detect past 60 fps or not. Of course higher framerates also affect input latency, so this news is relevant to the world of esports. Oddly, the news comes with a WORLD PREMIERE video showing the game running at 360 fps, which would not necessitate this change. The description does not explain, either:
Watch the first ever Overwatch 2 gameplay on GeForce RTX 4090 at over 360 FPS and sub 10ms latency, running at 1440p resolution with NVIDIA Reflex and high settings. Thanks to the incredible power of the GeForce RTX 40 Series, Overwatch 2 has increased its framerate cap from 400 FPS to 600 FPS. With the power of GeForce RTX 40 Series GPUs and NVIDIA Reflex, 360+ fps 1440p competitive gaming is now a reality.
