NVIDIA 450.57 is out for Linux with DLSS and NGX, Image Sharpening plus more

The thing I’m missing from nvidia right now is async reprojection support so I can play HL Alyx at high settings.

The thing I’m missing from any and all AMD-gfx systems I have (2 of them) is being able to boot every time I turn on the computer and being able to keep using it after I’ve booted.

Decisions, decisions.

There is also a new version of the driver from the Vulkan Developement branch out: version 450.56.01, see
https://developer.nvidia.com/vulkan-driver

Very tempting to install this one from the installer, though I'm afraid that removing it and going back to a driver from repositories fails. Does anyone has experience with that? Fedora 32 here.

Quoting: TheRiddickI'm quite excited about the future of DLSS because lots of other industries are noticing the huge benefits to such technology

I'm not. It's just a way to work around the lack of compute power that's needed for higher resolutions, and as usual it's overhyped by Nvidia. In practice, DLSS can't replace proper GPU compute units and if your card is lower end, your quality will be lower, DLSS or not.

To put it differently, DLSS is just another marketing gimmick, not a technology that can actually improve games quality.

Instead of overhyped gimmicks, GPU makers should work on improving compute power if they are so insistent that higher resolutions are necessary. Otherwise it makes sense to stick to resolutions on which image quality can be properly maintained.

Have you even tried DLSS 2.0? (and 3.0 down the pipe will be better)

Your comments strongly suggest you've only ever read about it or seen a very early version of it. Its NOT a gimmick and like I said, many industries are moving towards using lower resolution images to enhance to higher resolution with impressive results.

And it does improve quality, again, you're clearly someone who has not been keeping up to date with DLSS and other similar machine deep learning image enhancing tech's (basically same as DLSS but without NVIDIA drm).

Why not do both? MEME

Why waste compute power? games don't need loads of GPU compute power, ray tracing uses some of the compute potential, still room under the hood, use it.

Quoting: Avehicle7887In their own way Nvidia's Linux support is pretty good, and I've been mostly trouble free. There are however a few things which affect me and I also dislike, nominally having to re-install the driver after a kernel update (and I do those a lot), then there's the occasional issue with the driver refusing to install on latest kernels (my Nvidia system is still at kernel 5.5.19 cause of that).

The driver adapts automatically to a new kernel for me (thanks to DKMS I think).

*edit* I'm running kernel 5.6.14 on Debian Buster with backports.

So I've seen what NGX can do and the results are really stunning, mind blowing. Definitely a leap forward, at least from my amateur/consumer point of view.
But I wonder what this "support" means for us (Linux). AFAIK all the available software was Windows only. Granted, I didn't looked too much into it.
Is there any functionality (as of right now) available for Linux, or at least planned? I mean, the support was implemented for a reason, no?

DKMS will rebuild the driver from module source when required. This means that on rebooting to a new kernel, the first boot of that kernel may take a little longer while the module is rebuilt. Although Ubuntu and derivatives seem to rebuild all DKMS modules when the new kernel is installed rather than at boot (I don't know about other distros).

I've been running the Nvidia drivers on Ubuntu through manual install for a while now, if there's one thing I can say it's that Nvidia has been painless to install since... I dunno, 2002? That's when I started running Linux and Nvidia anyway - ATi was absolute bollocks on Linux then.

I don't have Nvidia cards. And yes, I've read various reviews which confirm what is really self explanatory. There is no magic replacement for compute power. If you increase resolution, reconstructed image can only be an approximation, no matter how much machine learning you'll throw at it. That's just how it works by definition.

So it doesn't increase quality, it only tries to mask its degradation due to compute power of the card not being adequate for a given resolution. That's a fake approach to quality and not something anyone should be cheering for. I'd stick to approach of matching given resolution with required compute power, not to gimmicks that degrade it.

Quoting: TheRiddickWhy waste compute power? games don't need loads of GPU compute power, ray tracing uses some of the compute potential, still room under the hood, use it.

Because I'm not buying some koolaid posing as quality.

Games that need more compute power can run at reasonable resolutions. Not in some overstretched mode with worse quality.

As he said you just missing the point. It does increase quality if you set lower settings.

Machine learning here is just kind of regression that predicts some pixels instead of calculating everything. And indeed it's not perfect like any type of interpolation.

Why do you want to waste energy power when you can have an almost as good render but with higher FPS ? What NVIDIA achieved is quite impressive and I can't imagine how long their neural network training must have taken.

Yes, obviously. Every computer graphic trying to mimic reality is an approximation, by the way.

The technology is better at creating a higher resolution image then current technologies by what I've seen. If you want to buy a card that can compute a 8K 240Hz resolution with supersampling anti-aliasing, nobody is keeping you from doing so.

I don't understand you negativity. What are you fearing?
