i've got 8gb of video memory and hundreds of milliseconds between clicking the mouse button down and moving the playhead. and even updating the player window every 100 milliseconds would be a huge improvement.

if you look at these old players they are actually doing all of these dirty tricks to make things responsive that you may be writing off in your head as not worth it.

Citation needed. Scrubbing is trivial when all your frames are I frames and requires no more memory or CPU than normally playing the video. It's literally zero extra code. That stops working when you introduce interframe compression.

the computer on the left is fast enough and has enough memory to store the entire video decoded as raw framebuffer in free video memory.

And if Chrome attempted to do that, then everyone would complain about how it's crashing their videogames while multitasking. Plus you'd have to cache aggressively to allow smooth seeking. And then it only works for HD videos up to 30 seconds which is what you can fit in there.

It's fun to complain that "modern software sucks" and that it "technically could do that" and that "computing is worse than it was", but no, sorry, this is all based on entirely reasonable trade-offs. What you're asking for is not reasonable.

modern software does suck. the player on the left does suck. there are players that don't suck that bad. but that's the one that's default on this computer.

No player is going to do what you want as smoothly as the old player on modern video formats universally, which is why many players make no attempt to pretend to do it. Yes, if you *really* want it, go use mpv and turn on exact seeks. It'll work, to varying degrees.
