Key takeaways

Rough session

Stutters cost a noticeable share of the playtime.

16 stutters (90 slow frames including 35 freezes) · 8.8 s lost

Main cause: Game computation (78 occurrences). The worst stretch cost 2.8 s of lost frames. 77% happened in the first ten minutes: the signature of shader compilation, which will not happen again on this game.

Pace set by the graphics card

The graphics card set the pace on 73% of the frames: the usual situation for an uncapped game.
