Builds a Proton-GE 11 / Wine 11 based compatibility tool for Elsword.
Uses Steam Linux Runtime 4 (soldier, appid 4183110).
Builds DXVK for both x86 and x64.
Produces release archives that other users can install into Steam.
Disables optional extras that are known to be risky for game stability by default:
- PROTON_DISCORD_BRIDGE=0
- PROTON_USE_OPTISCALER=0
- PROTON_USE_D7VK=0
- MANGOHUD=0
- ENABLE_VKBASALT=0

What this project does not do

No GameGuard bypass.
No anti-cheat bypass.
No patching or hooking of GameGuard.
No hard override of LOW_LATENCY_LAYER.
No global hard override of LD_PRELOAD.

Variant difference

Elsword-GE-11-1
- Proton-GE 11 base
- DXVK stable/latest release tag
Elsword-GE-11-1+dxvk-git
- Proton-GE 11 base
- DXVK from current upstream Git

NixOS prerequisites

Use the provided flake:

nix develop

The shell includes build dependencies such as:

git
bash
coreutils
findutils
gnused
gnugrep
gawk
jq
curl
wget
tar
zstd
meson
ninja
python3
pkg-config
cmake
perl
patchelf
binutils
mingw-w64 toolchains for i686 and x86_64
Wine / wow64 support

Local build

Build the stable DXVK variant:

nix develop -c ./scripts/build.sh stable

Build the DXVK Git variant:

nix develop -c ./scripts/build.sh dxvk-git

Build both:

nix develop -c ./scripts/build.sh all

Package both into release archives:

nix develop -c ./scripts/create-release-archive.sh

Output files

After packaging, the main release files are:

dist/Elsword-GE-11-1.tar.zst
dist/Elsword-GE-11-1+dxvk-git.tar.zst
dist/Elsword-GE-11-1-dxvk-git.tar.zst
dist/SHA256SUMS.txt
dist/release-notes.md

If + causes issues in a filesystem or upload target, the safe alias is:

Elsword-GE-11-1-dxvk-git.tar.zst

The Steam compatibility tool name still remains exactly:

Elsword-GE-11-1+dxvk-git

Install into Steam

Install a built archive:

./scripts/install-to-steam.sh dist/Elsword-GE-11-1.tar.zst
./scripts/install-to-steam.sh dist/Elsword-GE-11-1+dxvk-git.tar.zst

Generic installer for release archives, including Flatpak Steam users:

./scripts/install-compat-tool.sh /path/to/Tool.tar.zst
./scripts/install-compat-tool.sh --flatpak /path/to/Tool.tar.zst
./scripts/install-compat-tool.sh --all /path/to/Tool.tar.zst

Target path:

~/.local/share/Steam/compatibilitytools.d/

After install:

Fully restart Steam.
Open Elsword properties in Steam.
Select the matching compatibility tool.

Recommended Elsword launch options

The documented profiles live in profiles/elsword-launch-options.md.

Safe / GameGuard test:

LD_PRELOAD="" PROTON_DISCORD_BRIDGE=0 PROTON_USE_OPTISCALER=0 PROTON_USE_D7VK=0 LOW_LATENCY_LAYER=0 MANGOHUD=0 ENABLE_VKBASALT=0 VK_INSTANCE_LAYERS="" DXVK_HUD=0 %command%

Performance / low-latency test:

LD_PRELOAD="" PROTON_DISCORD_BRIDGE=0 PROTON_USE_OPTISCALER=0 PROTON_USE_D7VK=0 LOW_LATENCY_LAYER=1 MANGOHUD=0 ENABLE_VKBASALT=0 VK_INSTANCE_LAYERS="" DXVK_STATE_CACHE=1 DXVK_LOG_LEVEL=none %command%

Operational advice:

Disable Steam Overlay for Elsword if possible.
Do not launch with gamemoderun.
Keep MangoHud disabled.
Keep vkBasalt disabled.
Keep Discord Bridge disabled.
Keep OptiScaler disabled.
Keep D7VK disabled.
Test LOW_LATENCY_LAYER=1 separately.
If GameGuard kicks the game, go back to the Safe profile first.

Debugging

For Proton logs:

PROTON_LOG=1 %command%

Security and anti-cheat note

This project intentionally avoids:

GameGuard bypasses
anti-cheat bypasses
GameGuard patches
GameGuard hooks

The goal is only a clean Proton-GE build with complete DXVK payloads and conservative defaults for optional extras.
