Key takeaways

Bad session

Stutters cost a noticeable share of the playtime.

22 stutters (269 slow frames including 176 freezes) · 30.5 s lost

Main cause: Game computation (184 occurrences). The worst stretch cost 11.2 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 graphics card

The graphics card set the pace on 77% of the frames: the usual situation for an uncapped game.
