> We had OpenGL in the old days too. Pretty much straight from the beginning of the GPUs.
Someone missed out on the early PC days ;-) An example of what I'm thinking: Standardized-ish PC hardware (CGA, EGA, VGA, et al) might be abstracted by the programming language's libraries, but devs often reached below the abstraction, manually twiddling registers in the hardware. There weren't really standardized "drivers" for a lot of the available hardware.
OpenGL was opened in 1992, but it was only toward the late 90s that any (consumer-level) GPUs actually implemented it.
My apologies if you're mostly talking about non-consumer hardware.
I ignored PCs altogether. They were useless toys back then.
We had SGIs, so who cared about PCs?

And we're still doing it, nothing changed. Want performance and control - go low level. Want uniform APIs - use what your vendors are trying to feed you with.

An SGI station is still a kind of a "consumer" hardware.
Who's "we"? If you mean that they existed, then OK, I can't argue that. I've never known anyone that had one, but hundreds who had PC-level hardware.
>And we're still doing it, nothing changed. Want performance and control - go low level.
Low-level has changed significantly in meaning. Now maybe someone would try to go through the driver instead of the higher-level API, but no one's going to do direct register writes. Modern hardware isn't usable at that level.

Not a mainstream one by most measures, which is what I was trying to get at.
Not that much, actually, just shifted to the other domains.

You'd be surprised. People even do bit-banging now (could you imagine bit-banging a VGA port directly in the past?).

Is something like VC4 GPU modern enough? People do work with it on a very low level, thanks to the open specs. See this for example: https://github.com/mn416/QPULib
Actually, all the modern GPUs are getting simpler and more unifirm, so it's getting easier to hack them on a low level.
