at this point it might be better to overlay the packages onto pkgs but this remains a task for future me

# lsfg-vk-flake
|
|
Nix flake for using [Lossless Scaling's frame generation on Linux](https://github.com/PancakeTAS/lsfg-vk)
|
|
|
|
>[!IMPORTANT]
|
|
> You need to have Lossless Scaling installed on Steam!
|
|
> In case it is not installed on the default Steam drive, you may want to consider setting the correct path in the lsfg-vk config.
|
|
|
|
## Installation
|
|
### System-wide (NixOS module)
|
|
This approach will install an implicit layer to ``/etc/vulkan/implicit_layer.d/``
|
|
|
|
Add this to your flake inputs, output function and modules list:
|
|
```nix
|
|
inputs = {
|
|
...
|
|
lsfg-vk-flake.url = "github:pabloaul/lsfg-vk-flake/main";
|
|
lsfg-vk-flake.inputs.nixpkgs.follows = "nixpkgs";
|
|
}
|
|
|
|
outputs = {nixpkgs, lsfg-vk-flake, ...}: {
|
|
|
|
nixosConfigurations.hostname = nixpkgs.lib.nixosSystem {
|
|
...
|
|
modules = [
|
|
...
|
|
lsfg-vk-flake.nixosModules.default
|
|
];
|
|
};
|
|
}
|
|
```
|
|
|
|
And then enable this in your system config:
|
|
```nix
|
|
services.lsfg-vk = {
|
|
enable = true;
|
|
ui.enable = true; # installs gui for configuring lsfg-vk
|
|
};
|
|
```
|
|
|
|
### User install (manual)
|
|
1. Build the library:
|
|
```bash
|
|
nix build
|
|
```
|
|
2. Create the following path in case it does not exist:
|
|
```bash
|
|
mkdir -p $HOME/.local/share/vulkan/implicit_layer.d
|
|
```
|
|
3. Symlink the build results to your $HOME/.local/
|
|
```bash
|
|
cp -ifrsv "$(readlink -f ./result)"/* $HOME/.local/
|
|
```
|
|
|
|
## Usage
|
|
Run a Vulkan application with the environment variable ``ENABLE_LSFG=1`` set.
|
|
|
|
Example:
|
|
```bash
|
|
ENABLE_LSFG=1 vkcube
|
|
```
|
|
|
|
To confirm that it is working, look for output like this in the terminal: lsfg-vk(...): ...
|
|
|
|
You can also enable it per game on Steam by adding this to the launch options:
|
|
```
|
|
ENABLE_LSFG=1 %COMMAND%
|
|
```
|
|
|
|
>[!NOTE]
|
|
> If the environment variable is set but the program doesn't show any lsfg-vk output, you may need to add the application to your lsfg-vk configuration file at `~/.config/lsfg-vk/config.toml`. Read more about it in the [Wiki](https://github.com/PancakeTAS/lsfg-vk/wiki/Configuring-lsfg-vk) |
