Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

78 stutters (126 slow frames including 13 freezes) · 7.6 s lost

Main cause: Game computation (121 occurrences). The worst stretch cost 1.7 s of lost frames.

Pace set by the processor

The processor set the pace on 99% of the frames: it decides how many frames per second you get, not the graphics card.
