Decky LSFG-VK, the plugin that brings Lossless Scaling’s frame generation to Steam Deck and other Linux handhelds, just landed its biggest update yet. Version 0.14.1 is a ground-up rewrite built around LSFG-VK 2.0.0, and we want to walk you through what changed, how to install it, and how it performs across a few games.
What’s new in the LSFG-VK 2.0.0 update
This isn’t a small patch. The plugin has been reworked from the ground up to align with LSFG-VK 2.0.0, and existing v1 profiles aren’t compatible, so you’ll need to set up anything you configured before again. In exchange, you get a much cleaner layout: separate tabs for Steam Games, Non-Steam Games, Flatpaks, Settings, and an optional Config File view, with lists that automatically sort games into enabled and not-yet-enabled groups.
The biggest quality-of-life change is that you no longer have to copy and paste launch commands into every game’s properties. Enabling a Steam or non-Steam game now patches its launch options automatically while preserving anything else you already had in there, and Flatpak support has been reworked with per-app profiles and better detection, so there’s no manual pasting required there either. Enable All and Remove All actions are available for each category if you want to batch things.
There’s also a new Now Playing tab that automatically follows whatever enrolled game is currently running, surfacing just the controls that matter in real time, like FPS Multiplier, Performance Mode, and Flow Scale. It even works through Flatpak launchers like EmuDeck or Heroic, identifying the underlying app and exposing its frame gen controls live. Other additions include higher multiplier options for high-refresh-rate displays, FP16 acceleration moved into a global setting, and better cleanup when you uninstall.
How to install it
Getting set up starts on GitHub. Open a browser on your Deck, head to the decky-lsfg-vk releases page, and grab the plugin zip from the latest release. Once it’s downloaded, go back to Game Mode, open Decky Loader’s settings, enable Developer Mode, and use “Install Plugin from Zip” to point it at the file you just downloaded.
From there, you’ll need Lossless Scaling itself, which is a paid app on Steam. Open its properties, go to Game Versions & Betas, and switch to the “lsfg-vk” branch so Steam downloads the compatible version. Open the Decky LSFG-VK plugin, click Install lsfg-vk to set up the Vulkan layer, and then head into the Steam Games, Non-Steam Games, or Flatpak tabs to enable frame generation on whatever you want to play. Frame generation kicks in automatically once a game’s Steam AppID matches an enabled profile, no extra steps needed.
Worth remembering: this is still an unofficial community plugin, not something officially supported by the Lossless Scaling or lsfg-vk developers, so treat it accordingly if something breaks.
Performance impressions: hit and miss
We ran LSFG-VK 2.0.0 across a handful of games, and results were genuinely inconsistent from one title to the next.
In 007 First Light, we ran into visible ghosting and flickering around the character’s head and hair during motion. Running the same scenario with MAKO Frame Generation instead showed noticeably less of that artifacting, so this is one where LSFG-VK still has some catching up to do.
Cyberpunk 2077, on the other hand, is where LSFG-VK 2.0.0 shines. With it enabled, we were getting a clean, consistent 60fps, and pushing the multiplier to 3x (similar in spirit to adaptive frame generation) held up well without introducing much noticeable latency. If you’re looking for a showcase of what this plugin can do when it clicks, this is it.
Crimson Desert Enhanced was the rough one. Enabling LSFG-VK here meant missing the target frame rate along with noticeable latency and stuttering, and restarting the Deck didn’t fix it. That’s the “hit and miss” nature of this release in a nutshell: some games respond beautifully, others need more time to get sorted out.
Overall, LSFG-VK 2.0.0 is still early days for this rewrite, and it could use a few more updates to stabilize across the board. For now we’re still leaning on MAKO Frame Generation as the more consistently optimized option across our game library, but LSFG-VK is worth keeping an eye on as the devs keep iterating. Let us know in the comments if you’re seeing similar results on your own setup.
