Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

159 stutters (182 slow frames including 12 freezes) · 10.2 s lost

Main cause: Game computation (171 occurrences). The worst stretch cost 724 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.
