Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

98 stutters (170 slow frames including 9 freezes) · 7.7 s lost

Main cause: Game computation (160 occurrences). The worst stretch cost 1.2 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.
