Key takeaways

Rough session

Stutters cost a noticeable share of the playtime.

17 stutters (46 slow frames including 18 freezes) · 8.3 s lost

Main cause: Not enough RAM (36 occurrences). The worst stretch cost 3.5 s of lost frames.

Pace set by the processor

The processor set the pace on 98% of the frames: it decides how many frames per second you get, not the graphics card.
