Mekhoa ea optimization e sebelisitsoeng:
- Chrome 94 e fana ka mochine oa CompositeAfterPaint, o fanang ka ho kopanya likarolo tse fapaneng tsa maqephe a marang-rang 'me o u lumella ho phahamisa mojaro ho GPU. Ho latela data ea telemetry ea basebelisi, sistimi e ncha ea ho kopanya e fokotsitse latency ea ho bala ka 8%, e ekelitse karabelo ea mosebelisi ka 3%, e eketsa lebelo la ho fana ka 3%, e fokotsa tšebeliso ea memori ea GPU ka 3%, le ho lelefatsa bophelo ba betri ka 0.5%.
- GPU Raster, enjene ea rasterization ea lehlakore la GPU, e ile ea hlahisoa ho li-platform tsohle ka 2020 mme e potlakisitse li-benchmark tsa MotionMark ka karolelano ea 37% le li-benchmark tse amanang le HTML ka 150%. Selemong sena, GPU Raster e ile ea ntlafatsoa ka bokhoni ba ho sebelisa lebelo la lehlakore la GPU ho fana ka likarolo tsa Canvas, e leng se ileng sa fella ka tlhahiso ea kemiso e potlakileng ea 1000% le li-benchmark tsa 1.2% tse potlakileng tsa MotionMark 130.
- LayoutNG ke tlhophiso e ncha e felletseng ea li-algorithms tsa sebopeho sa leqephe ka sepheo sa ho eketsa ts'epo le ho tseba esale pele. Morero o reretsoe ho tlisoa ho basebelisi selemong sena.
- BlinkNG - ho lokisa le ho hloekisa enjene ea Blink, ho arola lits'ebetso ka mekhahlelo e arohaneng ho ntlafatsa ts'ebetso ea caching le ho nolofatsa ho fana ka botsoa, ho nahanela ponahalo ea lintho tse fensetereng. Mosebetsi o reretsoe ho phethoa selemong sena.
- Ho tsamaisa lisebelisoa, animation le li-decoding tsa litšoantšo ho arola likhoele. Morero ona esale o nts'etsapele ho tloha ka 2011 mme selemong sena o fihletse bokhoni ba ho romella liphetoho tsa animated CSS le litšoantšo tsa SVG ho arola likhoele.
- VideoNG ke enjine e sebetsang hantle le e tšepahalang ea ho bapala livideo maqepheng a webo. Selemong sena, bokhoni ba ho bonts'a litaba tse sirelelitsoeng ho qeto ea 4K bo kentsoe ts'ebetsong. Tšehetso ea HDR e kile ea eketsoa.
- Viz - mekhoa e arohaneng ea rasterization (OOP-R - Out-of-process Raster) le phetolelo (OOP-D - Out of process display composite), e arolang phetiso ea sebopeho sa sebatli ho tsoa ho phetiso ea litaba tsa leqephe. Morero o boetse o nts'etsapele ts'ebetso ea SkiaRenderer, e sebelisang li-graphics tse khethehileng tsa sethala (Vulkan, D3D12, Metal). Phetoho e entse hore ho khonehe ho fokotsa palo ea likotsi ka lebaka la mathata a bakhanni ba litšoantšo ka makhetlo a 6.
