[@meemee1357]

@@yyyyyeeeee4060 I was guessing the same thing, but I find it interesting that it wouldn't have the different mipmaps in memory. In source 1, VTF files have all the mipmaps in one file, and it appears to be the same for source 2. Seems weird to re-read the file every time.

[@M0rinkashi]

I like how the game enters random Arabic letters in the subtitles when it can't load the transcript up.

[@matthewdemarey4762]

@@M0rinkashi It honestly looked more like it was loading random bytes in place of the obviously missing text strings... I also saw Chinese characters in there so. Raw binary looks similar when loaded in a text editor, since all characters are just a set of hex bytes that the text editor decodes to show as something human readable. There are thousands of characters, mainly due to languages like Chinese, Japanese, Korean etc. with a few extras thrown in their from things like Cyrillic and Arabic. That said...it's odd. I wonder why anything was thrown into the CC (Closed Caption) box at all. Source certainly has its ways of remaining unique to this day lmao

[@ukkomies100]

@@matthewdemarey4762if it tries to retrieve the subtitles from the drive over and over again and just recieves the same error message bit string from the engine could it be displaying that? The different marks are propably because each subtitle would have located in a different memory location and the error it recieves propably includes that. And it is then interpreted as a character. Just a guess. Im not a programmer

[@matthewdemarey4762]

I'm honestly not sure, but it's an interesting guess! It's honestly almost like the error handling code is half there...that or that's just what the Half Life 2 build of Source does when the closed captions code runs into an null error. But I would say the former is most likely of those two options at least. I know programming fairly okay, I've just genuinely never seen such weird behavior before! Not that that's really unusual in this field lol

[@Pearl-Slug]

12:04 reminds me so much of a bug that used to be in older versions of Gmod. Back when you could still make traditional save games, if you saved on a map with NPCs you had spawned in and then loaded that save, sounds would get mixed up like this. I have a very distinct memory of loading a save in rp_silenthill where my footsteps made headcrab zombie sounds and firing the default pistol played the Father Grigori line, "Cover me, brother!"

[@JukoYT]

Lol, never knew about that

[@Tritone_b5]

[@hashajc]

Source 2 is kind of interesting, I guess with how sophisticated it is. Interesting how in HLA the already loaded in things were corrupting instead of corrupting when trying to load things.

[@JukoYT]

Yea, it is interesting how almost every game i tried acted differently

[@gb_2_]

Texture streaming and LOD

[@AFemmotaku]

Yes, like @gb_2_ hinted at, it's because of Level of Detail (LOD). As the character gets closer to an object the model updates to a higher quality version so it looks better up close but obviously doesn't need to look as good when its far away. The engine attempts to grab the texture from the drive, but as the USB is unplugged it causes a missing texture error.

[@fuji_films]

Might have something to do with update rates and more advanced graphics? It might be calculating stuff in real time so that could explain a few things, imo.

[@garfieldblessesyouwithadri3944]

@@fuji_films it's dynamically loading more resolution depending on how far away you are from said texture, this is called texture streaming as gb_2_ said, it trades a bit of CPU resources and potentially saves loads of GPU resources

I did some digging on the curious symbol that appears widely throughout L4D1's corrupted subtitles starting from around 16:10. Turns out, it's called "Right-Facing Armenian Eternity Sign" and has the code U+058D. It looks like this: ֍ This symbol has been included in Unicode since 2014 and represents a symbol that appears widely in Armenian religious architecture and in the modern day serves as a national symbol of the country, represented on the seal of Yerevan (its capital city), the logo of the People's Art Centre in Yerevan, the National Library of Armenia and a commemorative coin that celebrates the entry of the country joining the council of Europe.

What's interesting is how it generates these sounds, and maybe the developers put try and catch into their source code? Like in any programming languages there are error exceptions, that is, if an error occurs, then an exception occurs and the program continues to work

[@hyperixz]

the game begins to "bleed" out all the data and methods it uses to playback sound, so instead of playing a specific sound or showing a proper subtitle, it'll begin playing the RAW data of the audio file, you'll get the exact same glitch sound if you try to import that audio file into let's say Audacity as raw data. i call it "bleeding out until data loss" cause it sounds cool

[@Flare56]

What was most surprising is HDTF still being worked on

[@ukemi-]

Titanfall 2 uses the Source engine, would be interesting to see how it’d crash. Apex uses an adapted Source engine, would also like to see that in part 3. Halo (both MCC and OG releases) while not built on Source, would also be a nice choice to see what would happen.

[@vrad_exe]

It'd be interesting to try this with the xbox 360 versions of Source games as well, since it's possible to install them to the hard drive. An unmodded console will probably automatically close the game when the storage device is removed, but a modded console could probably bypass that.

[@stargost2338]

My best guess as to why HL:Alyx slowly corrupts around you is LOD (Level of Detail). It tries to load the lower or higher LOD models, but it fails. However, since it still has the general model for the object as well as its properties, the game decides to just go on without the higher resolution textures and models. Until it tries to actually fetch something it doesn't have, panicks, and crashes. The subtitles going crazy could be a result of them trying to read from a part of memory that doesn't exist, so it loads random chunks of code either from the game or other parts of the RAM thinking they are the subtitles. And my best guess for Dota, Artifact and CS is that since they are an online game, as soon as they detect something is wrong it crashes as a preemptive measure to avoid exploits or the use of 3rd party tools. And TF2 doesn't because it's TF2, a neglected spaghetti mess that is held together by 30 year old code, good intentions and the 2fort cow. It probably just ignores the lack of textures until it has to load something new, which isn't really surprising considering you can delete almost all texture and sound files and the game will still run, even in official matchmaking.

[@starbiifly6666]

A few suggestion for other Source games: Postal III Sin Episodes: Emergence Dark Messiah of Might and Magic Vampire The Masquerade Bloodlines G-String

[@jako8055]

Nice content. To expand the knowledge, the basic technical reason why your game is still running is because the game assets with all it's method and function is loaded into your RAM and VRAM. When you unplug your USB, the game experienced an error, looping, where there is nothing to load. Then the game will use the oldest jutsu in programming history to save your PC from bluescreen.
