PayPalThe dev of the popular Lossless Scaling app has been helping the lsfg-vk project that brings Lossless Scaling's Frame Generation to Linux to get it upgraded. Quite exciting news that GamingOnLinux shared recently, and progress on improving it has been ongoing.
Writing in the official Discord for Lossless Scaling, the developer behind the lsfg-vk project noted how they've had help from the original Lossless Scaling developer THS behind the scenes. Thanks to their help lsfg-vk has now been updated to support LSFG 3.1 (the latest version of LSFG).
As developer Pancake said on the Discord:
Update to LSFG 3.1
As promised the new version of lsfg-vk is updated to use LSFG 3.1, making it both faster and better!
When updating, make sure you change the branch on Steam back to the normal release branch.This new release also brings with it the
LSFG_FLOW_SCALEproperty, which can be used to override the flow scale from 1.0 (100%) down to 0.25 (25%). If you're encountering performance issues, you might want to consider lowering this option. Performance mode not yet supported unfortunately.
As part of the updates there's now a new LSFG 3.1 Benchmark you can use with instructions added to the Wiki.
Installing it should be a little bit easier now too, as the developer also announced they've enabled a GitHub workflow to build binaries constantly. However, it builds on Arch Linux so will only work on Arch-based systems. They've also made an installation script too but it still needs further testing and expanding to support more distributions.
Over time, as more people use it and help with it, I expect it to get a lot easier to use.
You can get it on GitHub for Linux but you do need to own Lossless Scaling on Steam.

Again, doubt it would happen. But it would be a nice addition I've seen plenty people ask about. Linux in general seems to lack some of those niche/more advanced features you can get on Windows. And unless AMD starts porting those features to Linux, Valve would probably be in the best position to push for feature parity themselves.

Are you just being a cautious pessimist, or do you have a reason why you doubt it will ever happen? It actually sounds like a really good idea and probably something that might ultimately be necessary if Valve is going to compete with these Xbox handhelds that are emerging, undoubtedly with full AMD driver and configuration software support.

Are you just being a cautious pessimistI guess I kinda am in that regard. Maybe I'll be proven wrong here.
That being said, I think it would be a bit of a unique situation. Since it's a proprietary application, it should ideally be Open Source so it can seamlessly be integrated into other projects like Gamescope and so that Valve has the ability to have more control over it instead of just paying for a license. (After all, that's kinda the situation with the Nvidia drivers right now)
But has Valve ever done something like that? They usually integrate projects that are already Open Source (MangoHud/FSR 1) but would they approach a commercial tool and propose something like that?
I think it would be a great idea. But over the last few years, it doesn't feel like that Valve is really pushing to close the gap in regards to features. Improvements, yes. But not really new features. HDR felt like the last big one. Maybe they're trying to convince AMD to port some stuff over. Maybe they're preparing all of that for the Steam Deck 2 as it would probably have much better hardware to fully utilize those features.
But we'll see eventually.

Some people are saying OptixScaler does a better job however.. not sure about that.
Also I wonder how this compares to NVIDIA Smooth Motion feature they have in the drivers.
Next step - official Linux support directly from the developer??
The developer is helping this project from what I've heard.

The LSFG dev actually explains why it won't happen here.

Well, the article here does mention this in the first sentence. Pretty sure they're talking about official Lossless Scaling support. And to that, I'd say that's what gamescope is for.
