Yup. Have to remember, the hardware accelerated encoder on the graphics/video card is typically used for real time video capture/encoding or video streaming. Quality will never be as good as software (eg. ffmpeg) CPU encoding. Granted, can still use the hardware GPU for manually encoding videos by specifying the hardware encoder using ffmpeg, but the quality will be far less than the software encoders... at least for now. I tested the nVidia GTX 670 GPU h264 hardware encoder some time ago when comparing h264 encoders, and immediately realized the only use was for real time streaming.
As far as the quality of the Intel Arc AV1 quality, shrugs, haven't compared the quality as of yet. Dunno when, here, ffmpeg will have access to the encoder. Once ffmpeg has access, there's usually more waiting until the zoom and other video chatting features implement AV1 hardware accelerated encoding.

I think there was an IP dump of Nvidia Ampere docs & code? I don't advocate nor participate in trafficking stolen IP, but it should mean there's information out there about some of their GPU internals.

It sounds to me like you're calling Intel lazy or incompetent, but I believe they're neither of those things.

It sounds to me like you're calling Intel lazy or incompetent, but I believe they're neither of those things. So, I'm trying to look for other factors and explanations to explain the current situation, and they're not hard to find. I'm sure that doesn't help you with your problems, but again I point to the monumental feature-set they're taking on. They don't just have to get everything working, but it has to be competitively fast and stable. That's more work than you think it is.

I use ICQ15/18 for 4k/AV1 and 4k/HEVC, CQP mode is just unreal, talking about bitrate/second
funny thing, their ASIC and software changed over the years, I always use the same source material for my ASIC tests, and even Intel qsv changed between iGPU and dGPU:
Code:Length Name ------ ---- 2319667940 docu.2018.1.ffmpeg.hevc_qsv_skl_icq_22.aac_nv12.mkv 1973101041 docu.2018.1.ffmpeg.hevc_qsv_dg2_icq_22.aac_nv12.mkv

X/Xorg with i915 modesetting driver only gives me displays going into power saving mode after starting X/Xorg.
Most seem to be having good results with Wayland/Sway.
