JuuTriubas kiek skirtingai veikia.. su Chromu gal net prasciau*..
Chromas issikviecia savo VP8, VP9 kodekus, kuriuos HW dekodint sunkiau..
Stats for nerds: Mime Type: video/webm; codec="vp9"

Mozilla defaultu berods kviecia HTML5 player'i, bet gauna:
Stats for nerds: Mime Type: video/mp4; codec="avc1.4d401f"
Su Flash'iniu player'iu (yra addons persijungimui tarp HTML5 ir Flash):
Stats for nerds lange: software video rendering; accelerated video decoding
Stats for nerds full_screen: accelerated video rendering; accelerated video decoding

Jei HW svieziausias, tai tarkim
https://en.wikipedia.org/wiki/Skylake_%28microarchitecture%29#Features

The integrated GPU of Skylake's S variant supports <..> some modern hardware
video encoding/decoding formats such as VP9 (GPU accelerated decode only),
VP8 and HEVC (hardware accelerated 8-bit encode/decode and GPU accelerated 10-bit decode).

Full fixed function HEVC Main/8bit encoding/decoding acceleration.
Hybrid/Partial HEVC Main10/10bit decoding acceleration. JPEG encoding acceleration for
resolutions up to 16,000×16,000 pixels. Partial VP9 encoding/decoding acceleration.[62]

Uz tat 5os ir 6os kartos CPU siuo klausimu nelabai snekasi po Win7.
