What is 99% FPS?

150 views

I installed a shader for Minecraft for the first time and I wanted to check how my computer was handling it, so I opened up NVIDIA’s Performance Overlay to see. It showed the FPS as a stable 59-60, but below it, something called “99% FPS” was swaying between 46 and 51. What does this mean, how does it differ from regular FPS?

It can be a bit confusing, but the FPS you normally see is the average frames per second you’re seeing. Some will be faster, some will be slower, but they average out to that number.

99th percentile is the minimum frame speed you should expect to see 99% of the time, as opposed to just “on average”. It basically means “you won’t see FPS lower than this, outside of an occasional hiccup”.
