Vulkan backend black screen #10

Closed rmalca closed 5 years ago

rmalca commented 5 years ago

In the sample "GettingStarted" when I change _graphicsDevice = VeldridStartup.CreateGraphicsDevice(window); for this _graphicsDevice = VeldridStartup.CreateGraphicsDevice(window, GraphicsBackend.Vulkan); I get a black screen without any warnings.

Any idea what it could be? Vulkan SDK Cube works fine.

The vertex data provided in that sample is "upside down" in Vulkan by default, unless an optional setting is enabled. This should work:

GraphicsDeviceOptions options = new GraphicsDeviceOptions() { PreferStandardClipSpaceYDirection = true };
_graphicsDevice = VeldridStartup.CreateGraphicsDevice(window, options, GraphicsBackend.Vulkan);

Perfect, it works now. Thanks!
