This Thume guy gets a lot wrong.
I'm not going to spend eons taking it apart: his ridiculous breadboard thing does not measure something precisely or accurately enough to be useful, and whatever it did measure he misinterpreted anyway.

> One disadvantage of the hardware accelerated video encode approach is that using minimal damage regions is tricky, because all you have is a vendor-provided API to encode new full frames into a video stream, and you can’t count on the vendor to optimize their encoder for large pixel-equal screen regions getting encoded very quickly.
This is just so far off base. Until he checked the "Enable H264 encoding" box, the stream was compressed on the CPU, to VP8. So it's not even hardware accelerated. It's just slow to compress on the CPU, period full stop, which of course scales with screen size much more than the dedicated compression hardware on their VMs.
The low performance has nothing to do with "minimal damage" regions, that provides no meaningful benefit to a hardware encoded stream. An H264/H265 P frame is much more optimal than a "minimal damage" region, it's like comparing spaceflight to a horse drawn carriage.
Large pixel equal screen regions are of course encoded extremely well in something like NvEnc and Intel QuickSync. What vendors is he even talking about?
> Does it constantly send 60fps compositor updates? No. A lot of apps make this mistake but Remotey doesn’t. If you mess it up it causes WindowServer to take an extra 10-20% CPU and extra power
This gets the biggest facepalm to me. This is the same crowd that thinks Unity games are slow because of "Gfx.WaitForPresentOnGfxThread."
Enough about Thume. The simple reason Mighty failed is that it MADE. NO. SENSE. Their latency could have been zero, and approximately zero people would have still used it. I'm not going to toot my own horn here, there are definitely streaming business that not only make sense, but make a HUGE amount of $$$ SENSE, but remote browser streaming isn't one of them.
