Key takeaways

Bad session

Stutters cost a noticeable share of the playtime.

42 stutters (1541 slow frames including 346 freezes) · 146.8 s lost

Main cause: Not enough RAM. The worst stretch cost 20.5 s of lost frames. 84% 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 84% of the frames: it decides how many frames per second you get, not the graphics card.
