Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

86 stutters (110 slow frames including 16 freezes) · 8.3 s lost

Main cause: Game computation (91 occurrences). The worst stretch cost 797 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.
