If anything, i suggest you try your skills with the old WinG32.dll games like shadow of the horned rat, would be interesting to see how GDI to Vulkan would work since the original HOMM1 and 2 patch did the same with GDI to direct 3d if i remember well

[@Dawnarow]

Cosmic brain is what is required for this... I wonder if blizzard could ever offer what the players always wanted for the current d2r game... that is potentially incredibly easy to accomplish:::::: Sell stash tabs. The game is "loot-oriented" and revolves around being able to trade. I'd keep el and elds to use a recipe nearly no-one uses if they were to do this and I'm sure they'd realize POE had the best structure for games... just offer what your clients want. Heck, if you don't want people to cheat, you can even offer them a "fake" 1-time purchase way to slap textures on your character's items via a "viewer" and just download images for your characters to display new graphics assigned to x-y items. Not selling "skins" but actually offering a way for players to create their own. Do you think you could make this, @nathanbaggs ? That'd be incredibly cool.

@@raelik777 Nah it just means any value 2^x. So 16x16, 32x16, 256x256, 512x512. But not 255x127. One small value and one big value ie 16x16 and 512x512. The LOD level determines the number of steps in between, also 2^x. So 32x32, 64x64 etc. Power of 2 numbers are very common in CPU/GPU processing. For example bit shift (basically x2 or divide by 2) is very cheap for CPUs ie costs little processing time as opposed to float divide/multiply.

[@dave7244]

One thing I would say about Glide is that even when it was way past it sale by date, it looked better than OpenGL and DirectX at the time it was just "smoother". No idea why.

[@AROAH]

Probably because it was created explicitly for Voodoo cards, so it could be perfectly optimized to work on that hardware.

[@dave7244]

@@AROAH I had a ATi 9800Pro and my friend had an older computer with a Voodoo 3 or 4 (one of the last Voodoo cards) and the same game had smoother animations on his machine compared to mine, even though my system was more highly spec'd.

[@SmallSpoonBrigade]

@@AROAH Yep, games back then were typically optimized for one chip or another. 3DFX got kind of lucky because the cost of memory chips took a nosedive after they did their designs and announced their initial cards. I think the only serious contender they had during those first couple years was PowerVR, but then they got entangled with Sega doing the chips for the Dreamcast and never got back to making cards for PCs.

[@Vatharian]

@@SmallSpoonBrigade Actually... they did! For a short while, at least. PowerVR was bought by Imagination Technologies, and was part of many ARM designs, but also... Intel's SOCs. For tablets. Remember that cheap tablet craze during Windows 8 era? These were PowerVR GPUs inside Atom SoCs. Thare was even short run of these SGX GPU chips on PCI-Express, but they were mostly development kits, and had exactly 0 public interest. Barely anything worked on it, since original GPU design hanged off of host chip's memory access, while ImT's design used very buggy and inefficient memory controller that could be paired with very, very narrow selection of memory chips, that went out of production at the same time the design hit the tapeout phase.

[@64fanatic]

Glide had a tilt-shift graphical effect missing in the other render API in Diablo 2. Using nGlide and restored EAX hardware audio (there's a few methods on modern Windows now) is *chef's kiss.*

We'd all probably be stuck on 4:3 25fps if not for it. I've gained a new appreciation for it after watching this.

[@asdf12337]

The 60 fps change was not programmed by PD2's team though. Still awesome they managed to add it (the original authors were hard to find I heard)! the 25 fps were giving me a headache over the last 2 decades whenever I came back to my all-time favorite game...

Fun video, thank you! Just an FYI, making an arbitrarily large array of texture samplers like you did and then dynamically picking one in the fragment shader is exactly what “bindless textures” is. So good job on making it bindless 😅

[@nathanbaggs]

There’s a specific bindless extension for Vulkan which gives you more flexibility, I feel like I cheated by just declaring a large array (:

[@Shimmen]

@@nathanbaggsthere’s one extension for allowing the large array to be partially bound and another for allowing dynamic indexing into the array in the shader (possibly more, can’t remember atm). However, in practice, enabling layers is more of a formality and while you’ll likely get validation errors the way you’re doing it now you’re still effectively using at least dynamic indexing even though it’s “illegal” :) so I’d say it counts, if a bit unorthodox

This was fun! A couple of things that may or may not be interesting When I was at Borland, we pronounced `_stdcall` "standard call" We also called it "name mangling" instead of "decorating" when it added the `_` to the exported function names. This term also applies to C++ symbols that get all the fun extra stuff tacked on as well.

I’ve always pronounced it “stood” same for the c++ standard library. Also yes I would use the phrase name mangling specifically for the process of differentiating overloads in C++ - but ultimately they’re all kind of the same process

Please continue this is nice! It's a well sized pet project. And the glide API seem not to be too large. The Pow2 stuff is probably cannot handle non-pow2 textures and the engineer who designed that API struggled a bit how to formalize this in C. Maybe you could record all the commands into a data-buffer and then once per frame when you flip you process that "recording" so you have more context, can batch more, process the buffer in multiple passes and synchronization should become also easier.

[@cianmoriarty7345]

6:13 creating different windows with different resolutions for different parts of the game is absolutely what it does. Back in the day you used to hear a definite click from your CRT monitor when it would change resolution as it went into different parts of the game such as the splash screen, the cinematics, the game itself. Probably because back then it was probably_much_ easier to change resolution than to rescale a (for the time) high bandwidth prerendered video.

I did get the render distance bug fixed though by trying to force it to try and read the d3d9, and adding triple buffering in the INI file. However if we could get modern direct-X or Vulkan working it would be a game changer. Most people playing AC though unfortunately are completely okay with playing it on a original CRT screen, and have no interest in making the game look better. So working on this alone has been a headache as I have to pioneer, and figure it out on my own. Good luck to you though on getting DII to render in Vulkan; you're almost there.

Graphics programming is and always has been a particular witchcraft even by programming standards. It was complex enough back in the Glide and OpenGL days, these days... who knows.

Wow! Great work so far! Can't wait to see more progress into this! Don't give up!

I did a Computer science course, mostly creating and editing databases, which in a sense most games are, but never got into graphics or hardware. It's been years since I've programmed anything and I'm completely out of my depth with current software, but watching this I could feel some of it coming back. The enjoyment of even just editing a text file and seeing it appear in the running game. I may have to create something some day soon.

Now do this for Sacred Underworld! There are older patches for it but none of them work great on modern-modern hardware either. Fantastic work with this video.

Very interesting topic. Thanks for sharing! Remind me when i was reverse ingeneering protocols to communicate with old devices that was left unsupported and making them compatible with present protocol. And GL with synching if you ever do, that really doesn't sounds fun with at all :D

Having recently spent at least a day trying to render a single triangle with Vulkan, i appreciate this video.

[@yah3136]

Nice video, lot of memories (3DFX/GLIDE and Diablo). Hope you will continue this serie, I would love to see the final result. Thank you

[@RenninganEA]

- I'm a software developer (Android-Java) - I have no idea whats happening for 95% of the video - I'm waiting for part 2

[@ulior28]

Came for the coding stayed for the "VUK" error out of date "kahar" and "wuz" popup, keep it up bro!!!

[@greatemeraldoz]

I may be stupid here but wasn't d2 remastered with modern graphics? I mean I bought it and played it. Graphics seemed pretty modern and you can even hit a button and see what it looked like back in the day. Please explain to me the difference.

[@orestes_io]

This is such an interesting video. Love the debugging skills, the research, the ingenuity. good stuff!

[@D4rkS7der]

Really cool! I enjoyed this video quit a bit! Will you please make second part of this? Btw.: are there gonna be t-shirts with smallLodLog2? :D

[@thantul]

great video! very appreciate the work you've put into this and takes me back to my C++ graphics classes

[@ThatKidBobo]

Downloading a Glide Wrapper and using it improves Diablo 2 alot. It'll be interesting to see what this improves over that way of playing.

[@sebastianramadan7863]

There exists the concept of largest object, which is a sequence of contiguous bytes. It tends to vary from storage duration to storage duration, though I'm convinced mmap transcends mere ISO-compliant storage durations. Structs may contain implicit padding after the first element, between elements and/or at the end. We're kinda meant to serialise them to some expected format but 🤷‍♂️ that be less time for shopping

[@Bobbias]

While I do appreciate the smallLodLog2 joke, I do hope that was purely for comedy's sake. Its quite clearly the base 2 logarithm of the largest dimension of the lowest resolution mipmap. How hard is that to understand?

[@LinguisticMirage]

Not everyone has 100% energy at all times to understand. Even i sometimes dont understand simple text if im tired enough

[@phitsf5475]

ok smartypants

[@bide7603]

I really do hope this comment is for sarcastic effect…

[@Bobbias]

@@bide7603 facetious at best, but yes.

[@8manifest143]

Really interesting video. Not a good programmer, but conceptualizing things in the particular way you bring them to light, is thought provoking. Thanks for sharing!

[@RaisinsO]

Even though I did not understand anything, it was fun to watch and listen to the explanation. Thanks!

[@RawFish2DChannel]

I always wanted to do something like this, I tried to do the same with Red Alert 2, but it's using software rendering, and without a lot of modifications it's impossible to hook it up to modern graphics API... It's probably possible to modify game code for that, but I'm not good at reverse engineering and reading raw assembly to figure out what game does. There are also few other very old games I want to try it on, like Cutthroats: Terror on the High Seas (great game, buggy, with outdated graphics, but very good and hard game) and Corsairs Gold, haven't checked how they render stuff yet. Great video, subscribed 👍

[@ScandalistRick]

Nathan, thank you for highlighting how truly minimal my computer/coding knowledge is. I need to switch to something light, let me go take a look at the quantization of energy and the probabilistic behavior of energy quanta... Or something...

[@S1ckbg]

This is exactly the kind of videos youtube loves to show me at 4 am in the morning and i live for it
