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.




Comparing both these memory kits with low graphical settings helps show how the sub-timings can affect the frame-rate in the 1% lows, and the average.




Increase the graphical settings, Forza Horizon 5 quickly starts to be more dependent on the GPU.




Raising the game's resolution to 4K and Forza Horizon 5 becomes completely GPU bound, leaving the CPU often waiting on the graphics card to finish each calculation. With a margin of error of 5%, these two memory kits are indistinguishable at this resolution using a RTX 4090.
