Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

51 stutters (69 slow frames including 15 freezes) · 5.6 s lost

Main cause: Not enough RAM (37 occurrences). The worst stretch cost 781 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.
