github.com/Devaniti/D3d... D3d12info, D3d12infoGUI and D3d12infoDB now updated to support the new DirectX 12 Agility SDK 1.618.1, incl. "tight alignment" support.

This new video by Timothy Lottes will be the craziest way of programming you've seen for a long time. www.youtube.com/watch?v=RrL7...

Why the @#&! there is no VK_BUFFER_USAGE_ACCELERATION_STRUCTURE_SCRATCH_KHR_BIT and I need to manually consider minAccelerationStructureScratchOffsetAlignment? If there was such flag, vkGetBufferMemoryRequirements could return required alignment.

A great write-up about additions to Direct3D 12 API that happened throughout 10 years since it was first released.

This is the project I've made solo during Slavic Game Jam 2025. Nothing fancy, not even a game, just 5 interactive shaders, to learn how to do custom GLSL shaders in Godot (incl. temporal feedback). Source code included. reg-697500.itch.io/shader-symbi...

Debugging AMD-Specific Issues with Driver Experiments Tool - new article on my blog. asawicki.info/news_1788_de...

It seems that videos from the talks from Game Industry Conference 2024 started appearing on their YouTube channel. Some interesting content there. www.youtube.com/@RPGPP/videos

I'm writing a tutorial about Packer Plugins for Total Commander to support a custom archive format. I've put sample code on GitHub. Any feedback is welcome. github.com/sawickiap/To...

Hardware virtual textures look like a marvelous tool for large terrains or volume compression. Alas, they are in a sad state in terms of performance and usability. And strangely, the (very bad) binding perfs varies a lot with the driver. → read here: hal.science/hal-05138369 @rcmz0.bsky.social

ZTGK competition was full of great games made by teams of students. I am grateful for inviting me to the jury! Some games were made using ready engine (usually Unity), with a separate category of games made on a custom engine (typically in OGL, with editor made in ImGui).

Microsoft recently released DirectX 12 Agility SDK 1.616-retail & 1.717-preview. Let's see what's inside. 🧵👇 devblogs.microsoft.com/directx/agil...

I just published my new article: The Secrets of Floating-Point Numbers asawicki.info/articles/sec...

I've been thinking for years about writing a tutorial on developing a Total Commander file system plugin - so you can easily browse, pack, unpack, and edit custom archive formats. Would anyone be interested in that?

After years of continuous development, we just tagged a new release of D3D12 Memory Allocator library v3.0.0 🎉 🏷️ So if you want the latest and greatest D3D12MA, or just more info - head over to GPUOpen! #Direct3D #DirectX12 gpuopen.com/d3d12-memory...

In today's new blog post, I try to provide some intuition and clear up some misconceptions about early Z cull behavior on desktop GPUs. Have a read if that interests you! therealmjp.github.io/posts/to-ear...

Friday evening thought: If the minimum amount of digital data is 1 bit and the typical word size these days is 64 bits, why the base addressable unit of data is still 1 byte = 8 bits? Does it make any sense other than tradition and ensuring backward compatibility?

Having a GPU crash in your DX12 or Vulkan app on AMD card? New Radeon GPU Detective (RGD) 1.4 now shows which draw calls were executing shaders during the crash, assembly (ISA) of those shaders, and which instructions were executing (instruction pointer). gpuopen.com/learn/hardwa...

🚀 Today is AMD RDNA 4 day! To celebrate, we've got new content on GPUOpen: 🔥 Machine-readable ISA for RDNA 3.5/4 🔥 #opensource Interactive Streaming SDK 🔥 Updates to AMF + Capsaicin Find out more: gpuopen.com/learn/new_co...

According to the #LunarG 2024 Ecosystem Survey Report, over half of all developers surveyed use our Vulkan Memory Allocator (VMA) library for their #Vulkan development 🎉 Thank you for your trust and support! 🥰 VMA: gpuopen.com/vulkan-memor... Survey: lunarg.com/2024-ecosyst...

DirectX 12 Agility SDK 1.716.0-preview Explained - a new post on my blog asawicki.info/news_1783_di... #directx12 #dx12

New update to D3d12infoGUI - github.com/Devaniti/D3d... Updated Agility SDK + now also using AMD device_info library for additional (and more reliable info about AMD cards) Thanks to bsky.app/profile/asaw... for Updated to D3d12info

I added support for the new #directx12 #dx12 resource tight alignment to D3D12 Memory Allocator. Because it is a preview feature, I did it on a branch: github.com/GPUOpen-Libr...

The new DirectX 12 Agility SDK 1.615.0 and 1.716.0-preview adds some exciting features! I plan to write more about it on my blog soon. D3D12 Memory Allocator library and D3d12info tool will need an update. devblogs.microsoft.com/directx/agil... #directx12 #dx12

A little #DirectX12 tip: Passing NULL to Map/Unmap means you want to read/written entire resource. Passing empty range like {0, 0} means you plan to read/changed nothing. Know the difference and use it properly. If you don't, it won't necessarily work wrong, but just to be formally correct...

I’ve written down some thoughts about C++ and how a better programming language could look like: docs.google.com/document/d/1...

New update to D3d12infoGUI - github.com/Devaniti/D3d... Finally added table with format support flags

I wish tools that display CPU usage scaled it by number of cores/threads instead of using percent of all. It would be clearer to see my 16-thread Ryzen CPU used by a single-threaded app as "1.0/16" rather than "6.25%".

An interesting opinion I've heard: Programming talks on gamedev conferences are problematic because even the ones explaining some basics are understandable to programmers only, while talks about game design or graphics are more or less understandable to everyone.

Vulkan 1.4 integrates and mandates support for many proven features into its core specification, expanding the functionality that is consistently available to developers, greatly simplifying application development and deployment across multiple platforms. Learn more: khr.io/vulkan14

A friend of mine said every time he works in an office, he observes nearby construction site to see what will be finished first - that building or the software they develop. So far the building always wins.

Traveling back from Code::Dive conference in Wrocław... It was mostly about C++. It was great to watch Bjarne Stroustrup, Herb Sutter, and other talks live. Very inspiring.

If people tend to link to a GitHub repository as the main page of a project, I think GitHub should display formatted README first, not the list of files and the description of last commit.

It is not convenient for lexicographical sorting that "before" starts with "b" and "after" starts with "a" rather than the other way around 😀

Software development tip: When something stops working: Best: Not let that happen, use tests. Average: Find whose change introduced the regression, revert it, tell him to fix and submit again. Worst: Add it to the bug tracker for someone else to fix.

I think that games moving from the model of one big release to soft launches and regular post-release updates is a good thing because it makes game development more like other software development rather than like movie making.

Discussion panel about game development for multiple platforms. Q: Was programming for PS3 really that bad? A: PS3 made a whole generation of programmers afraid of multithreading. #gic24 #gamedev

Object-oriented code can be a mess with lots of layers and all the "managers", "wrappers", "helpers" and other "-ers", but so does data-oriented code with many levels of indirection, indices, handles, "data", "info", "descriptor" structures.

I can't understand why so many people insist on putting space after if⋅(condition) but not after Function(arguments). It's so inconsistent.
