Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Technical Issues Large Black Patches on Ground

Was it working in earlier versions?

For the Steam version, did you try verifying local files? In the Steam library, right click on Divinity Original Sin and select Properties, switch to the Local Files tab and then click on the 'Verify Integrity of Game Cache...' button.

Have you tried changing video options in the game (texture, resolution, display mode, etc)?

In your graphics drivers, did you try setting the 3D options to default, or at least anti-aliasing to application controlled?

Did you check for updated video drivers?
