Realtime demos

category: general [glöplog]
 
It's sad that everybody watches demos from youtube nowadays. Myself included. It's so much easier.

But it's also somehow more real when the images are pixel sharp and the machine isn't fast enough to execute some javascript software renderer and it lags a little bit. This is pretty much lost when the medium is youtube.
ha! we had that issue of lag in one of our demo (mundane) but honestly, it's also part of the charm.
Haha yeah, I am tempted sometimes to watch or sneak peak from YouTube as a bad habit. Then I download the demos for later watch and I forget to watch. Only when I organized demo watching marathons on real hardware it feels good.

Add more interactive elements, such as user-modes to play around with parameters, and some people might be more inclined to actually run the demos. :)

the best part of using youtube instead of realtime is skipping all the boring parts!
Imagine skipping all the boring parts of a scroller demo
Youtube also has far better controls than my Amiga. You can pause, rewind, ff, etc.

But it's not realtime anymore.

My C64C doesn’t support YouTube.

Am I the only one who thinks that YouTube is, all things considered, a good and proper way to watch demos?

The author has created the demo for a particular target machine. If the viewer has a matching machine (whether it's a PC with a recent GPU or some oldskool machine), great. But most viewers do not.

Watching a good capture on YouTube gives a viewing experience that is both more authentic and closer to the author's intent than running it on a too slow machine or an emulator.

But then people came up with emulator captures.

No, there just isn't much to say about it, so I guess many people who are fine with it don't.

and with current GPU prices you need a mortgage to run a new fairlight demo

For me the problem is thanks to LLMs, its prohibitly expensive to upgrade GPUs to compensate for demos.

So Youtube is kinda needed, and for my own personal code? Need to make compromises.

Absolutely, and its only getting worse :(

1. Obtain mortgage
2. Buy two GPUs
3. Wait half a year
4. Sell one of the GPUs
5. Pay back mortgage
6. Profit

Nope, many probably agree with you. But then again many people are also fine experiencing forests by looking animated images of forests.

Just saying that actually running the executable and knowing that the program, with it's flaws, runs right there on your computer, is different experience than watching a video of it.

Oh absolutely, the experience running Fairlight's "Ceasefire", was the experience that my GPU was going to melt at the time (it didn't but ran it just fine, but the intentional glitch effects really scared me.

It was awesome, now since I am running on AMD, some demos barely run at all (even my own, so I got to do "remasters" basically).

Not really the subject here, but the convo sorta went there: perhaps a cap on hardware specs could be considered due to current situation? Or am I spewing nonsense. Or is it a whole new subject?

or just watch the video
(also, no new fairlight demos anyway, so, no worries there! :P)
It is like porn. The real thing is usually more complicated, but also more satisfying.

Heh. And I thought my "images of forest" comparison was already a bit too much.

I mean, I totally agree it's nice to able to watch demos without the hardware. Especially with PC demos I usually just watch the YT videos.

But still, it's different since code physically runs right there. On your computer. With videos it's just the generic depacker. (Usually streaming a file from someone else's computer.) The generic depacker doesn't even reproduce the pixels 1:1. Especially any high frequency particle detail gets totally lost.

Also from sort quality PoV, does the demo crash or not? If that wouldn't matter, why indeed, just not make a video?
(note: I used the term "crashing" in very broad sense. For example, how well different scenes run, is just as interesting)
