since version 0.9.0 PancakeTAS provides prebuild Arch packages as well (https://github.com/PancakeTAS/lsfg-vk/releases)

Same Problem what Pulec and Yok0ri described: Radeon 6800S and/or Radeon 680M (tested on both). Installed, even reboot, "vkcube" gives me a segfault. Deleted every "VkLayer_LS_frame_generation.json" and "liblsfg-vk.so" and reinstalled, didn't work. "conf.toml" directly copy-pasted from Wiki-Page.

Not working, seems that "r247.614a2a1-2" is broken for me...

EDIT: Installed directly from Git-Source, everything's working. Something's wrong in this AUR-Package...

Same issue as Yok0ri has segfault at trying to play anything in mpv or even launching qutebrowser.

I was thinking it's because new * nvidia drivers (using 4070 super), but all works fine on everything updated at the current time of writing and using older lsfg-vk-git-r199.e67fcd3-2-x86_64.pkg.tar.

If anyone wants this specific package, write me on IRC.

Otherwise, it works amazingly, Cyberpunk 2077 on all ultra and path tracing. 12GB VRAM is too little for 2560x1080 for more than a few minutes of gameplay, though; it just gets filled up, better on 1920x800 (21:9 res ftw). Otherwise, old games like C&C Generals with a silly 30 FPS limit, the framegen makes it super smooth.

Ok, so, I am writting a comment here to tell you that after the recent update (r247.614a2a1-2 on July 26 2025) this package somehow breaks Zed editor for me, causing a segfault.

I spent half an hour downgrading kernel and different Zed dependencies, but then ChatGPT told me to trace system calls with strace, and it led to conf.toml, the config file for lsfg-vk. After removing the package or its config file, Zed starts opening normally.

I am writting it here because installing it from the source (curl command on git) works fine. So it is clearly an issue with the AUR package, right?

error when installing

CMake Error at CMakeLists.txt:19 (add_subdirectory):
The source directory
/home/kami/.cache/paru/clone/lsfg-vk-git/src/lsfg-vk/thirdparty/volk

If download of "volk" is not working in version lsfg-vk-git-r240.247d7cb-1, do this:

cd ~/.cache/paru/clone/lsfg-vk-git/src/lsfg-vk/

git submodule update --init --recursive

And than update again.

After r197.b2205f3-1, it works now.

Have the same problems:

spirv-headers is missing as a build dependency

Samueru commented on 2025-07-10 05:27 (UTC)

You might wanna make the post install script check ${XDG_DATA_HOME:-$HOME/.local/share} instead of having it hardcoded to check ~/.local/share.

both lsfg-vk and steam check and use XDG_DATA_HOME.
