[–] dasenradman@lemmy.zip 37 points 3 months ago (6 children) What are they refering when they say "1%"? permalink fedilink source hideshow 6 child comments replies: [–] SomGye@sh.itjust.works 89 points 3 months ago (2 children) In game benchmarks, a lot of sites and reviewers tend to show the bottom 1 percent of framerate in their graphs, so the 1% here would be the lowest/worst part of the average performance. Boosting the 1% would essentially be raising the minimum performance and make performance drops less severe. permalink fedilink source parent hideshow 2 child comments replies: [–] Cris_Citrus@piefed.zip 29 points 3 months ago (1 child) Thank you for explaining! permalink fedilink source parent hideshow 1 child comment replies: [–] SomGye@sh.itjust.works 9 points 3 months ago You’re welcome! 🙏 permalink fedilink source parent [–] Creat@discuss.tchncs.de 33 points 3 months ago (2 children) To clarify further: They aren't saying "1%" they are saying "1% lows". If you only take the bottom (lowest) 1% of all frame rate measurements (and average them), that is what this refers to. The reason this is important is that it gives a good indication if a game "feels laggy". Occasional dips to low fps or stutters in general will lower this number. permalink fedilink source parent hideshow 2 child comments replies: [–] Ghoelian@piefed.social 9 points 3 months ago And to add even more, the reason this is important, is because in-game fps counters/overlays use an average over a short period. Quick lag spikes can make a game feel horrible while the counter displays a solid 60fps. permalink fedilink source parent [–] kevincox@lemmy.ml 2 points 3 months ago If you only take the bottom (lowest) 1% of all frame rate measurements (and average them) I don't think that is the methodology. I think it is taking the 99th percentile frame time. So basically if took the time it took to generate every single frame this is the time that 99% of frames were faster than and 1% were slower than. If this number goes down it means that the worst frames are less bad. This is a pretty important part of the experience as even if you have good average frame time (and decent FPS) having a few slow frames really makes the game feel choppy and can make precise inputs difficult. permalink fedilink source parent
