According to the creator of lsfg-vk:
A couple of hours ago Deck Wizard has made a video on Lossless Scaling in which they present a new Decky plugin for lsfg-vk. On Reddit, the creator of that plugin claimed they had collaborated with me to create this, however this is incorrect and was likely the result of a language barrier.
I was asked to collaborate, but I instead requested them to wait with the plugin until the new configuration system was written, as otherwise a large portion of the plugin would have to be rewritten to account for it. They did not listen and pushed the plugin out without communicating with me beforehand.
As a result of this, the plugin already has many issues such as incorrect labeling of options and misleading descriptions of other options. Likely in collateral, the video created by Deck Wizard further spreads these wrong explanations. I want to clear up these things. First of all, the settings recommended by Deck Wizard are 30% flow scale and no performance mode. I can not state enough how terrible these options are. With 30% flow scale, internal calculations are happening in 96x54 images with some going down to 2x1, producing extremely inaccurate results. Instead, it is recommended to keep flow scale at 85-100% with performance mode enabled, as this gives a much larger performance boost while retaining immensely higher quality.
Clearly all of this is simply a result of poor communication and as such I will not support the Decky plugin. Do not ask about help with lsfg-vk when using the Decky plugin. Perhaps in the future an official lsfg-vk Decky plugin can be made in actual collaboration with me. Pancake - Developer of lsfg-vk
The plugin is still the easiest way to use Lossless framegen ATM, but it's definitely worth knowing about this.
Looks like there was an update:
Update 7/14/25: Pancake has just posted a new update on the Decky Plugin controversy on the Lossless Scaling discord server:
Hello everyone! I'd like to clear up some things after the previous announcement, which caused way too much unnecessary drama.
Behind the scenes, I've been talking to both Deck Wizard and Kurt (xXJSONDeruloXx on GitHub), who is the creator of the Decky plugin. The situation we got into was caused purely by poor communication, so we sat down and discussed the future of the plugin together.
Let's get into the news then. The Decky plugin will remain unofficial and unsupported in this discord, not as a means to discourage using it, but rather to keep the growing load of support away from me, as I have barely anything to do with the plugin. Together with Kurt and Deck Wizard we've fixed the major labeling issues in the plugin, as well as created an update video on Deck Wizard's channel that you can watch here: Future support with the Decky plugin will happen in the Discord server linked in the video description and depending on which category your issue falls into, you may be forwarded to this discord instead.
In the future, some pretty big changes will be coming to lsfg-vk which will likely require a portion of the plugin to adapt. I will be working with Kurt to get the changes into the plugin as quickly as possible, however this warrants a whole other announcement and I can't promise any timeframe (it could be hours, days or weeks).

Thanks for sharing, that's a great additional bit of info on this whole thing.
