Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

122 stutters (179 slow frames including 5 freezes) · 7.1 s lost

Main cause: Game computation (176 occurrences). The worst stretch cost 1.1 s of lost frames.

Pace set by the processor

The processor set the pace on 97% of the frames: it decides how many frames per second you get, not the graphics card.
