Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

Main cause: Game computation (16 occurrences). 89% 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 87% of the frames: the usual situation for an uncapped game.
