Client Configuration

The client reads GMP_Config.toml from the current game working directory. If the file is absent, GMPC writes a default one. If parsing fails, it logs the error and uses defaults for that launch without overwriting the broken file.

The current client reads only the settings documented below. Old installations may still contain removed keys; they have no effect.

Player Settings

Setting	Default	Runtime behavior
nickname	""	Player name. An empty value triggers first-launch setup; the menu limits input to 24 characters.
language	0	Zero-based entry in Multiplayer/Localization/index. The shipped order begins with English (0), Polish (1), and German (2).

The in-game options menu is the normal place to change both values. Editing the index manually is useful mainly when a localization file fails to load or the menu cannot be reached.

Window And Console

Setting	Default	Runtime behavior
[window_position].x / .y	absent until known	Restores the game window when both coordinates are positive. Used only in windowed mode.
window_always_on_top	false	Keeps the SDL game window above other windows in windowed mode.
[console_position].x / .y	absent until known	Restores the external debug console when both coordinates are non-negative.
debug_console_enabled	true	Creates the external console used for logs and console commands.

The client normally writes both position tables itself. If a monitor-layout change leaves either window off-screen, remove that table and let GMPC create a new position.

Graphics

Setting	Default	Valid values	Runtime behavior
renderer_type	"D3D9"	"D3D7", "D3D9", "D3D11"	Renderer selected during startup. Unknown values leave the D3D9 default active.
vsync_enabled	true	true, false	Initial VSync state passed to the selected renderer.

Use D3D9 as the normal starting point, D3D7 for the original Gothic renderer or third-party renderer wrappers, and D3D11 only when testing the incomplete native backend. See Renderer for compatibility and troubleshooting details.

Developer Integration

Setting	Default	Runtime behavior
mcp_pipe_enabled	false	Starts the local \\.\pipe\GothicMCP named-pipe bridge. It is development tooling and should remain disabled for normal play.

Removed Settings

The current client no longer reads log_chat, chat_lines, watch_enabled, watch_position, or [test_mode]. Chat presentation and the watch are now implemented by Lua resources, and the old built-in test-mode configuration was removed. Delete these keys from stale configurations rather than expecting them to affect the client.
