Introducing AMD GI-1.2 with multibounce indirect real-time rendering - AMD GPUOpen AMD GI-1.2, our real-time Global Illumination solution, is available now as part of the AMD Capsaicin Framework v1.3.

Capsaicin is not just for tacos, it's also our developer rendering framework!

v1.3 is out now:

🌶️ Added heat with GI-1.2, which includes multiple-bounce indirect lighting.
🌶️ HDR support with spicier tone mapping.

And much, much more: gpuopen.com/learn/gi-1-2...

Only 26 minutes? Fiiiine, I’ll rewatch PsychOdyssey then.

YouTube video by People Make Games The Rockstar Workers Fired Before They Could Finish GTA 6

I went to meet the 'Rockstar 31', the developers who were suddenly fired from their work on GTA 6 for what the studio has described as gross misconduct.

That's not what the workers call it though. They have another couple of words they prefer to use: union busting.

This was such an amazing experience! Now I want to play MGS2 again!

Absolutely adored Keeper! @leepetty.bsky.social and @doublefine.com have done an amazing job!

Still thinking about the Blood Incantation gig in London…

After quite a bit of work, I am finally done with the first blog post about ocean rendering! You can find it here: rtryan98.github.io/2025/10/04/o...

I've also decided to create a video to showcase the ocean simulation in motion: www.youtube.com/watch?v=0OXm...

New blog post! In "Billions of triangles in minutes" we'll walk through hierarchical cluster level of detail generation of, well, billions of triangles in minutes. Reposts welcome!

Ten Years of D3D12 For those of us that have been using it from the start, it can be hard to believe that Direct3D 12 has been around for nearly ten years now. Windows 10 was released on July 29th 2015, and D3D12 has be...

I've got a new blog post for all of you fine folks! It runs through the additions to D3D12 since it was released, and finishes up with some of the things that have changed for me personally in my code.

(And yes it's really been 10 years 👴).

For quite a while I've been working on a Fast Fourier Transform based ocean simulation in my render engine.
Whilst there is still a lot to work on, I'm excited to see the result once I've added IBL to this renderer.

Weapons was such a great movie. My favourite of this year so far. Go see it with the biggest audience possible. It’s a total blast!

Yeaaaah…there is a lot of bias in the deferred path that I haven’t gotten around to fixing. I just wanted to get it working again first haha. But I am hoping to improve on it later on and bring it closer to ground truth.

It’s been on-hold for a while. Had difficulties remastering the textures since you really need PBR materials to make it shine (no pun intended hehe). Might get back to it at some point though!

Get ready for FSR Redstone with AMD FSR 3.1.4 and our new UE 5.6 plugin - AMD GPUOpen Integrate AMD FSR 3.1.4 to get ready for FSR Redstone, updated Unreal Engine 5.6 plugin now available.

AMD FSR Redstone is our upcoming suite of ML-powered AMD #FidelityFX neural rendering technologies.

🟥 Get your game Redstone ready with #FSR 3.1.4 🟥

We've also updated our #UnrealEngine FSR 3 & Radeon Anti-Lag 2 plugins to support UE 5.6.

Back in 2021 I released a Vulkan sample that demonstrated adding ray-tracing to a traditional game render pipeline. Since then the code has rotted away and stopped working. So this week I finally resurrected it! Hope it will keep being a learning resource for beginners.

Do you like heavy riffs? Do you like Hatsune Miku? Boy, do I have the song for you by @bitbreaker.bsky.social !

My favourite is probably “It’s behind you Tyronne, whenever you reverse things come from behind you” 😂

“Oh dogs! Sure…I like dags”

That’s actually a really solid build, especially the CPU 😉

That’s very sweet of you, must’ve been fun! I’m surprised you could build a PC for that much at all these days.
