#Frame generation not working on Linux Mint

Here's an overview of my system that's running Linux Mint 22.3 on X11:

GPU: Radeon RX 7800 XT
Driver: Mesa 25.2.8-0ubuntu0.24.04.1 (LLVM 20.1.2)
Kernel: 6.17.0-14-generic
Steam install type: native .deb install
Proton version: GE-Proton10-32

My goal is to limit in-game FPS to 60, then generate rest of the frames to match my 144 Hz monitor. I followed the lsfg-vk installation guide exactly, and the Vulkan layer appears correctly:

VK_LAYER_LS_frame_generation (Lossless Scaling frame generation layer) Vulkan version 1.4.313, layer version 1

However, frame generation does not seem to work. After trying to get it to work on Steam games, I learned of a way to test using vkcube:

ENABLE_LSFG=1 LSFG_MULTIPLIER=2 LSFG_DLL_PATH="~/.local/share/Steam/steamapps/common/Lossless Scaling/Lossless.dll" vkcube

vkcube runs normally and does NOT slow down, which suggests LSFG is not injecting.

Any ideas what I might be missing?

What does the terminal output say when using vkcube?

It says: Selected GPU 0: AMD Radeon RX 7800 XT (RADV NAVI32), type: DiscreteGpu

echo swan
#

It looks like it's not even installed. Remove the config file and start vkcube first. Only:
vkcube

#

That made the cube slow down, nice! Does that mean it will now work elsewhere?

#

because as of now, Steam games still don't seem to work...

echo swan
#

If Steam isn't working, it might be because Steam is Flatpak, and you would need to follow the Flatpak-related instructions on the wiki.

#

And tell me how you're trying to apply lsfg to Steam games.

echo swan

with %command% ?

hollow linden
#

Sorry, what command?

echo swan
#

LSFG_PROCESS=RE8 %command%

hollow linden
#

One moment

#

That was it, thank you!

#

It's strange that "Configuring lsfg‑vk" page on GitHub doesn’t include that %command% argument. Perhaps it should be added to avoid confusion?

echo swan
#

no

#

%command% is steam thing only

#

heroic, lutris, terminal dont need this

#

Good to know, thanks again!

@hollow linden were you able to interpolate from 60 to 144 FPS? I've been wondering if its possible to do the same thing

echo swan
#

just 60 to 120

#

or 144/3 using multi x3

old rock

okay thanks
