Intel have open source drivers too for their graphics so that will be great.And critically they manage to get support lined up well in advance of the launch of their hardware, which AMD have historically struggled with.

Quoting: EikeWell, not quite Geocities' heyday, but it was a while ago. It was the PS3 era, and MySpace was the world's biggest social network. AMD had a really terrible open source driver and a really terrible proprietary driver (I won't say the name in case it triggers flashbacks), and were selling off their fabs because they'd run out of money. Intel was switching to the Core architecture after the failures of Netburst and Itanium. YouTube was full of videos showing off Compiz, and Ubuntu had released a "Long Term Support" version called Dapper Drake.Quoting: CatKillerThe PPUs definitely existed. I doubt that many got sold, because the business case for them was rubbish, but you could get pre-built gaming machines with them in. The technology was also in a bunch of console games before Nvidia bought Ageia.I googled and found some... on Geocities. (So that's the age we're talking about. :D )

The AI for DLSS 1 needed to be trained on "what this game should look like" to provide its results, and the per-game magic numbers were included along with the per-game optimisations in the fat Windows driver.
The AI for DLSS 2 is trained on "what games look like" and the one set of magic numbers is used for everything.
Devs need to include motion vectors and the previous upscaled frame in their engine to use the DLSS mechanism for the next frame.

Quoting: TheRiddickHowever gamedevs still need to send off textures to NVIDIA for processing, but maybe one day developers will have access to those tools themselves and NVIDIA won't need to be involved (we can only hope).They don't.

Quoting: x_wingIIRC, the first sample of Physx I saw was on 2005 and it was from the former company that created the tech, using dedicated hardware, which was in a very early stage (I'm almost sure that their dedicated solution never got to the market).

In the moment that Nvidia bought that company, their strategy was to implement that solution into the GPU. So, Nvidia wanted to move physics calculation into GPU as use case of GPGPU.Of course they did. Buying an extra PPU was silly, but GPGPU is great. And of course they wanted it to be a market differentiator to make back the purchase price, particularly as Intel had just bought Havok at the time.

Quoting: x_wingSo, the idea was to accelerate physics execution using the GPU but their reluctance to make a standard made them fail and 15 years after they first release of Physx we are still using the CPU.No, the idea was that you'd buy a separate card just for accelerating physics calculations. But that was silly: no one was going to buy a card just for that, and no one was going to put support into their game for something that no one had. So Nvidia bought the company and made it so that you could run those calculations on the GPU that you already had. Then they open sourced it some time later.

Quoting: GuestAs far as I know, FSR is basically a couple of shaders? So I wonder if it could be injected to any game via something like vkBasalt. Pretty sure it wouldn't be quite something so simple. Suppose I should read up on it more to know if that would be viable. It'd definitely be very cool if it was, just from a technical perspective, even if I wouldn't really benefit much personally from this kind of thing.If it has some particularly tasty rescaling algorithms, a nicer place to pick it up would be gamescope if, say, there were some performance-constrained AMD hardware that was habitually upscaling.
NVIDIA 470.42.01 for Linux adds DLSS for Proton, Xwayland, asynchronous reprojection

Added gsp.bin firmware file which is used to offload the GPU initialization and management tasks on some GPUs.I wonder if this will help or hurt reclocking with nouveau. Hopefully the former.

Quoting: slaapliedjeGranted, nvidia doesn't support Mac at all, which I still find amusing.They can't. On Windows and Linux, the GPU vendor provides the API implementation. On Macs, Apple do. Apple and Nvidia had a falling out, so no more Nvidia hardware in Macs, so no support from Apple for Nvidia hardware in Macs.

One thing that would be interesting is if Intel licensed the DLSS tech from Nvidia. They do have the hardware, since they're chasing the same machine learning market as Nvidia. Tensor cores on consumer products is essentially a lemons -> lemonade situation. On the one hand they won't want to give Intel a leg up in the dedicated GPU market, nor in the very lucrative machine learning market, but on the other hand a feature that both Nvidia and Intel have that AMD doesn't will put the squeeze on their mutual competitor.

Quoting: ShmerlSo instead of being essentially a fancy display, the headset will have its own GPU?Standalone VR headsets already exist with their own GPU. The Oculus Quest uses the Adreno 540 and the Quest 2 uses the Adreno 650. In terms of graphics power they're pretty weak, but going stronger risks melting your face. The idea of this is that you can offload some of the face melting stuff to a different machine, but have enough local processing power that the latency doesn't make you hurl.
That moves things into interesting direction of eventually rendering everything on the headset itself, but I guess they need to get small enough first while being powerful. Current GPUs required for VR use a ton of power and need serious heat dissipation.
