Frametime Analysis

We present a more in-depth analysis than just average FPS to show how the framerate changes over time, which helps highlight FPS drops. Minimum FPS at both the 95th and 99th percentile are reported in these charts, too. A second chart, a histogram, shows shape and spread for the frametime data—how tightly grouped the measurements are. The "IQR" result is called "Interquartile Range," which is an outlier-resistant statistical value that tells us the range in the middle of the frametime distribution.




Doom Eternal using a highly optimized game engine, which helps computers with a weaker processor. Still, under the right configurations, the frame-rate gap can still be observed even with some of the more powerful hardware currently available to PC gamers.




Raising the resolution to 4K and the gap shrinks. Add in a 5% margin of error for good measure, and the two memory kits are fairly close. However, the second chart shows the Corsair memory kit lagging a bit behind in the total frames generated in each bar for the second half of the bell slope.
