Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

156 stutters (275 slow frames including 11 freezes) · 12.2 s lost

Main cause: Game computation (272 occurrences). The worst stretch cost 1.6 s of lost frames.

Pace set by the processor

The processor set the pace on 99% of the frames: it decides how many frames per second you get, not the graphics card.
