Today NVIDIA put up a rather exciting blog post talking about RTX - with Arm. Not only that, they've showcased it using Linux too which is pretty amazing.

Shown off for the Game Developers Conference, NVIDIA has announced an expansion of their RTX SDKs to support to Arm and Linux. What they've added in includes support for:

  • Deep Learning Super Sampling (DLSS), which uses AI to boost frame rates and generate beautiful, sharp images for games
  • RTX Direct Illumination (RTXDI), which lets developers add dynamic lighting to their gaming environments
  • RTX Global Illumination (RTXGI), which helps recreate the way light bounces around in real-world environments
  • NVIDIA Optix AI-Acceleration Denoiser (NRD), which uses AI to render high-fidelity images faster
  • RTX Memory Utility (RTXMU), which optimizes the way applications use graphics memory

What they presented was an NVIDIA GeForce RTX 3060 GPU paired with a MediaTek Kompanio 1200 Arm processor, setup with Arch Linux (likely something like Arch Linux ARM) along with testing out the likes of Wolfenstein: Youngblood.

“RTX is the most groundbreaking technology to come to PC gaming in the last two decades,” said PC Tseng, general manager of MediaTek’s Intelligent Multimedia Business Unit.“MediaTek and NVIDIA are laying the foundation for a new category of Arm-based high-performance PCs.”

Multiple companies sounded quite excited by it including Epic Games, Machinegames and Unity.

There's also a separate post from NVIDIA to properly announce the new NVIDIA DLSS SDK, which adds full Linux support including for native x86 Linux games and Arm too. Quite an exciting move for the future of Linux. The DLSS SDK is also easier to get now, with no application to NVIDIA required as you can do a direct download now.

Quoting: dvdThis whole thing is so fake, it's not like making/compiling drivers for other cpu architectures is anything new. On the contrary, this should be the bare minimum for all the arches out there. I wonder whats the profit angle on this one.

Making drivers for other architectures is a piece of cake?
You're serious?

Quoting: F.UltraConsidering how quickly they managed to port Wolfenstein Youngblood to not only Linux but also ARM Linux shows that those rumours that they had DOOM running natively on Linux way back where highly likely true.

Yes exactly, having the driver ready for ARM is one thing, showing an ARM port of an AAA game is at least equally impressive (and serves indeed food for lots of rumors :)).

switch has ARM hardware and it has AAA titles all over
afaik switch runs freeBSD which is kinda linux
so i think its not that hard to make a switch ARM TITLE run on LINUX ARM

The switch port was handled by an external company though, Panic Button, the demo on Linux ARM seams to be inhouse?!

does it make any difference? the game and all of its source codes are property of bethesda, so why would they do it all over again?

First of all not sure if the porting contracts works that way (wasn't there a game on Stadia where there did exist a native port but the studio rewrote their own native port for Stadia alone), and only means that they have a build for the Switch SDK which is it's own thing and not FreeBSD.

I didn't say that. It's pretty ridiculous: these are companies that rake in revenues by the billions, and they act like they just invented the printing press, when in reality all this is just them finally giving a damn about other architectures. It's not like 10-20 years ago they didn't have people to write the exact same driver for any architecture they wanted to.

Ok, I missunderstood you than. Yes, they could if they want (ed) to.

Quoting: MohandevirWhat is making me wonder it's the fact that Microsoft and Nvidia always walked hand in hand, when it comes to gaming... What is happening?

I guess they also just want to be future proof. Nvidia is working with Valve (enabling DLSS on Proton) and Nintendo on the Switch etc.

Is the Switch bit still valid?
I thought that was some rumour for the Switch Pro which obviously didn't happen.

There's been rumours of a pro since before it got released, completely disregarding that the development of software for the switch already had to account for the split in the "slower" (mobile) and "faster" (docked mode) versions from the very beginning.

I'm sure that the pro rumours will continue right up to and after what nintendo has brewing for the next gen gets released, whatever that might be.

Quoting: Purple Library GuyWhat I'm wondering is if industries like say animation might be looking at moving towards ARM and that might be part of what's driving this kind of thing.
That's a good point. I mean the death of SGI was because Intel+Linux was simply more powerful for lots of $$$ less. If cheap ARM clusters can just offload rendering to racks of GPUs in a data center, it'd be even more profound of a thing. Of course the tools themselves to create the art to send off to the render farms still needs to perform decently enough.

I also wonder how much Microsoft announcing a cloud based Windows version is going to influence things. Or if Microsoft themselves is going to try and kill off installed versions of Windows and just recommend their own Linux to run their cloud Windows... We have weird times ahead.
