Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

55 stutters (81 slow frames including 5 freezes) · 4.7 s lost

Main cause: Game computation (80 occurrences). The worst stretch cost 1.5 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.
