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 uses a highly optimized game engine, which helps computers with weaker processors. 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. Here we see a 22 FPS difference in the average and 15 FPS for the 1% lows.




Raising the resolution to 4K, the gap shrinks, leaving a small gap for the 1% lows. Depending on the game, those frames will be missed. Still, at these graphical settings, it should be a smooth gaming experience.
