Agree. Same for SIMD instructions, and video decoders.
Too many libraries/frameworks are trying to software emulate what's not supported, and fail miserably because the emulation is not remotely fast enough.
- namibj 6y agoGood example: youtube.com It doesn't realize that H.264 1080p60 works due to HW decoding, and falls back to VP9 480p30 because it ties 720p and up to HFR if it's an HFR video. Using `youtube-dl -F` will tell you that 480p, 720p30, 720p60, 1080p30, and 1080p60 are available in H.264, while only higher resolutions are gated behind VP9. Some videos (from 50 Hz countries) are p25/p50 instead, but iirc using the same format codes as the p30/p60 brothers.
