Key takeaways

Rough session

Stutters cost a noticeable share of the playtime.

18 stutters (495 slow frames including 64 freezes) · 36.7 s lost

Main cause: Game computation (404 occurrences). The worst stretch cost 10.8 s of lost frames. 97% happened in the first ten minutes: the signature of shader compilation, which will not happen again on this game.

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.
