Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

345 stutters (431 slow frames including 31 freezes) · 26.8 s lost

Main cause: Game computation (403 occurrences). The worst stretch cost 973 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.
