Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

5 stutters (8 slow frames) · 0.2 s lost

Main cause: Game computation (7 occurrences).

Pace set by the processor

The processor set the pace on 96% of the frames: it decides how many frames per second you get, not the graphics card.
