Linux gaming is faster because Windows APIs are becoming Linux kernel features

https://www.nxp.com/docs/en/reference-manual/M68000PRM.pdf see page 292, also see page 629 for the table of "exception vectors" (addresses for code to handle each specific trap/exception/interrupt)

Most processors support both "interrupts" (an external peripheral is banging on the CPU's interrupt pins... but also invocable from software; software interrupts; SWIs; INT instruction on x86) and "exceptions" (e.g. divide by zero, bus error, illegal instruction). Depending on the processor, accessing the "privileged" mode can be done either by software interrupts, exceptions, or both. An operating system should pick one and stick with it.

Other uses for interrupt/exception/trap vectors include hardware breakpoints: don't try and single-step the CPU, overwrite the code with an illegal instruction and control will flow to the illegal instruction handler where you can see all the registers then execute the real instruction that was meant to be there and return to where you left off. Some CPUs have a formal "BKPT" type instruction for that.

One other use on the 68000 is that any unrecognised instruction that started $Fxxx triggered the F-line handler; all the floating point instructions were in the form $Fxxx, so if you didn't have an FPU, you could put a software emulator for the FPU instructions in the F-line handler and software wouldn't know the difference. Traps/exceptions don't have to be a jump from unprivileged to privileged, they can just be utilitarian.

You could be more like Plan9, Linux. You could actually innovate and create new paradigms that make people look at MacOS and Windows and think that they are no longer in the same league.

But you don’t want to do that. You want to play games faster.

Fucking children run the world today. There are no adults keeping track of things making sure that as we go forward that things make sense. There’s no adult supervision in the computing industry anymore. None. It’s all just profit margins calling all the shots. Asinine.

How did it turn out for windows, being “The OS for Games”? Not great, I’d say. Windows is quickly losing that title and will soon become more and more irrelevant for gaming. If you focus on games until you’re “The OS for Games” then decide to innovate on real things that matter outside the home, then you’ll lose that title just like Microsoft is losing it now, and it will happen a lot faster for you than it did Microsoft, because the Linux community is about as organized as an Oklahoma town recently destroyed by a tornado.

Games are fast enough for anyone and there are certainly enough games today that if 5 people lived for 500 years each, there’s not enough time for them collectively to play all games that are available today.

I don’t know what you gamers think the “end game” is for games. Graphics? When are you meant to be happy? When will you stop and say, “ok, we made it”?

Graphics. Pfft. Games do not get better with more realistic graphics, and you know it. Great games are great because they are well thought out and well tested. Great games are not great because the shadows are sharper or because the reflections are more accurate. Some of the shittiest games ever look amazing, and some of the shittiest looking games are S-tier. And you all know it.
