Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

433 stutters (530 slow frames including 43 freezes) · 32.1 s lost

Main cause: Game computation. The worst stretch cost 536 ms 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.
