Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

33 stutters (67 slow frames including 11 freezes) · 4.2 s lost

Main cause: Game computation (67 occurrences). The worst stretch cost 1.2 s of lost frames.

Pace set by the processor

The processor set the pace on 100% of the frames: it decides how many frames per second you get, not the graphics card.
