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.
Switching over to Forza Horizon 5, we can see from the charts that a frame gap does exist. If your graphic card can crank out the frames, this game will benefit with higher frequency system memory, affecting the frame-rate in the 1% lows, and the average.
Increase the graphical settings, depending on the game, this may be enough that we are once again GPU bound and rely on the graphics card. However there is a still a small gap between the two memory kits.
Raising the game's resolution to 4K and now, Forza Horizon 5 becomes completely GPU bound, leaving the CPU often waiting on the graphics card to finish each calculations. With a margin of error of 5%, these two memory kits are indistinguishable at this resolution using a RTX 4090.
