What is 99% FPS?

151 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?

The average render throughput is 59-60 FPS. Because this is an average, there will be frames that were quicker and frames that were slower.

The 99% FPS is the throughput if every frame was as slow as the remaining slowest frame if the 1% of slowest frames is ignored.

Or inverting the numbers, a 99% FPS of 46 means that 99% of the frames took 22ms or less to render.
