=== Assistant: A black-screen in Warlords Battlecry 3 on Linux Bazzite using Heroic + Wine/Proton is a known issue. ===
A black-screen in Warlords Battlecry 3 on Linux Bazzite (using Heroic + Wine/Proton) is a known issue. It’s usually caused by one of these:

===== In Heroic: =====
# Heroic → Settings → Wine Manager
# Install Proton-GE (e.g., GE-Proton 9 or whatever is newest)
# Go to the game → Settings → choose the Proton-GE version you installed
# Launch again.

WBC3 often works better with custom Proton builds.

===== Some people get a black screen because DXVK struggles with this old DirectDraw/DirectX 8 title. =====

In Heroic, under the game’s settings:
* Scroll to Environment Variables
* Add:

<syntaxhighlight>DXVK_DISABLE_D3D10=1

</syntaxhighlight>

Or completely disable DXVK:
* Toggle "Disable DXVK" (if available)
* Or add:

<syntaxhighlight>PROTON_USE_WINED3D=1

</syntaxhighlight>

===== Through Winetricks (Heroic → Wine Tools → Winetricks): =====

Install:
* d3dx9
* vcrun6
* directplay (sometimes required for old games)

===== Sometimes it boots black in fullscreen. =====

Try editing the game’s config:
# Go to the game's install folder
# Edit Battlecry.ini
# Find or add:

<syntaxhighlight>Windowed=1

</syntaxhighlight>

Or launch with the argument:
-w

===== Bazzite uses Wayland by default; some older games work better under X11. =====

Try launching Heroic with XWayland:
# In Heroic game settings, add environment variable:

<syntaxhighlight>WINEDLLOVERRIDES="ddraw=n,b"

</syntaxhighlight>

This forces a better fallback for DirectDraw.

===== ✔ which Proton/Wine version you're using =====
✔ logs (Heroic → Show Logs)
✔ game settings or config file
