DirectX 12 Ultimate Announced

Microsoft announces DirectX 12 Ultimate, which will bring new technology they've developed for Xbox Series X to PC. This includes inline ray tracing, variable rate shading, mesh shaders, and sampler feedback, and they offer a deep dive to explain each of those features. They also offer with reassurances that this will not impact game compatibility. Here's the overview:
Microsoft’s Game Stack exists to bring developers the tools they need to create bold, immersive game experiences, and DX12 Ultimate is the ideal tool to amplify gaming graphics. DX12 Ultimate is the result of continual investment in the DirectX 12 platform made over the last five years to ensure that Xbox and Windows 10 remain at the very pinnacle of graphics technology. To further empower game developers to create games with stunning visuals, we enhanced features that are already beginning to transform gaming such as DirectX Raytracing and Variable Rate Shading, and have added new major features such as Mesh Shaders and Sampler Feedback.

Together, these features represent many years of innovation from Microsoft and our partners in the hardware industry. DX12 Ultimate brings them all together in one common bundle, providing developers with a single key to unlock next generation graphics on PC and Xbox Series X.

Only until the last gen or two, the consoles always took the lead on PC's for a small period of time. I'm glad they push the PC's, if they surpass the PC's will soon catch up and gives us a good reason to upgrade.

8 core 16 thread Ryzen 3000 CPU and a Pci-e 4,0 M.2 SSD is significantly better than what 90% of PC gamers play on, probably a higher % than that...

It's going to take a lot to get all of the PC master race upgraded to 8-core CPUs, let alone Pcie 4.0 SSDs... This feels like a big jump (it's amazing), and better not lead to downgrading the scope of new games to keep the poor PC in the loop. I want them to just push this new tech, and let's see what it can do, give people a REASON to upgrade.

On the bright side, since Sony is being so much more ambitious about pushing the I/O envelop than MS, multi-plats won't be using their PCI-e 4.0 specs as a baseline. Pop in an existing and already cheap NVME M.2 drive and you're more or less on par with what the new Xbox hardware is capable of.

You're correct, so we shouldn't even be talking about the 5.5 GB of PS5, but the 2.5 GB of XboxNeXt.

But Microsoft is using hardware decompression just like Sony is, they just haven't done a deep dive on it. I can't remember the new buzzword for it, probably something like "hardware IO decompression ultimate" =p

But @KilrathiAce, Even a "normal" 500 MB /sec SSD is going to be woefully underpowered. Even without fancy decompression, we're talking a 500% boost for the xbox with 2.5 GB/sec. If a game is designed from the ground up for this spec, something that's 20% (at best) as powerful simply won't be able to play the game. Try playing GTA V off a 5400 RPM HDD running at 20% speed. It's not really possible.

Expect another update when they adapt the PS5 storage I/O pipeline into a chip for motherboards for PC gaming in the next few years if their promise of a "loadless" paradigm for 1st party titles turns out to be true.

Would be nice having this bottleneck removed from PCs too. Right now something prevents taking full advantage of NVMe drives, this tech removes those bottlenecks, but it requires a new chip and new programming protocols.

But the elephant in the room is that the PC is now the lowest-common denominator in gaming, we're what's holding developers back.

As for DX12 Ultimate. I guess Marketing felt a big word was better than .1 or something. Good to see new features, no matter how they name it.

Yep I'm looking forward to whatever these consoles do better, that being brought to the pc and improved.

Devs won't even bother with Dx12 on the PC (well, only a few do).
I hope the new DLC will cause a migration once next-gen console games are made.

Speaking of game streaming with PS5 off the SSD at 5.5GB/s, that was just the base speed (although I'm sure Queue Depth 1-4 is much lower like most NVMe in the 60MB/s range). They said with Kraken compression they can hit 9GB/s. Since PCs won't have this speed anytime soon it'll push PC games to have much higher RAM usage to avoid streaming. Probably fine since PCs typically have 16GB+ RAM and 8GB+ VRAM, more than next-gen consoles, albeit maybe a bit slower than GDDR6 for now.

Between storage performance and this separate Tempest audio processor it's very interesting. Imagine having HRTF on 100s of audio sources in every game. It's really going to sound next-gen. Very few PC games do that because it's CPU intensive and this is offloaded entirely to the Tempest.

I'm skeptical that it will require a new chip. I'm sure it can be done with firmware and offloaded to the CPU.

But the elephant in the room is that the PC is now the lowest-common denominator in gaming, we're what's holding developers back.

With it's billions of spindle drives and non-M.2 SSDs, the PC platform is now a massive liability for game designers. Pretty hilarious turn of fate. I'm surprised I haven't seen any Op-Eds tackling this irony, it's all I've been able to think about for the past few days.

How do you even program a game that's meant to use 5.5GB/sec transfer speeds for 80% of your sales (on console) and still somehow have it work on a PC with a 100MB/s spindle drive (check steam hardware stats, there's lots of em), or even a traditional 550MB/sec SSD? We're not talking about reduced loading time, the game itself just wouldn't work, there would be huge hitching ALL THE TIME.

So stuff like sharing the new console spec features with the PC is great, I mean variable rate shading is a gamechanger for people looking for high-fps high-rez gaming (will be getting a 1440p 240hz Samsung G7 when it launches).

A new paradigm, we´ll be hearing more of this.
May be a practical PCs and PC Pros divide.



Change min requirements for game to run off ssd for starters.
