Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

23 stutters (47 slow frames including 2 freezes) · 1.6 s lost

Main cause: Graphics load (37 occurrences). The worst stretch cost 270 ms of lost frames. 100% 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 91% of the frames: the usual situation for an uncapped game.
