Key takeaways

Smooth session

The time lost to stutters stays below the threshold.

15 stutters (25 slow frames including 3 freezes) · 1.2 s lost

Main cause: Game computation (24 occurrences). The worst stretch cost 320 ms of lost frames. 76% 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.
