Renderer
GMPC can start Gothic through three renderer paths. Choose the renderer in GMP_Config.toml with renderer_type, then restart the client.
renderer_type = "D3D9"
vsync_enabled = true
Renderer Choices
| Value | Best use | Notes |
|---|---|---|
"D3D7" |
Vanilla compatibility, troubleshooting, and external renderer wrappers | Uses Gothic's original Direct3D 7 renderer. GMPC does not replace the renderer in this mode. |
"D3D9" |
Normal play | Default GMPC renderer. It supports modern resolution handling, but the client still marks it as experimental because visual glitches are possible. |
"D3D11" |
Testing only | Native GMPC Direct3D 11 path. The client warns that it is not fully implemented. |
For most players, start with D3D9. If the game fails to start, crashes during video initialization, or renders incorrectly, switch to D3D7 and test again. Use D3D11 only when you specifically want to test that backend.
External Renderers
Third-party Gothic renderers such as GD3D11 and LegacyAltRenderer expect Gothic's original rendering path. Use renderer_type = "D3D7" when testing those tools with GMPC.
Do not combine GMPC's native D3D9 or D3D11 renderer with a separate renderer wrapper unless you already know that wrapper supports this setup. Those modes replace Gothic's renderer instead of leaving the original path untouched.
VSync
vsync_enabled is read from the same config file. The exact effect depends on the selected renderer and graphics driver. In the D3D9 path, changing VSync may require a device reset or client restart before the result is visible.
Troubleshooting
| Symptom | First check |
|---|---|
| Black screen or crash on launch | Set renderer_type = "D3D7" and restart. |
| External renderer wrapper does not load | Use D3D7; native GMPC renderers replace the original Gothic renderer path. |
| Tearing or uneven frame pacing | Toggle vsync_enabled and restart the client. |
| Visual glitches in normal play | Try D3D7 to separate renderer bugs from server or script issues. |
When reporting renderer issues, include the selected renderer, whether VSync is enabled, your Gothic version, and any external renderer or wrapper you are using.
