Fermi and Kepler DirectX API SupportAnswer ID 3196 | Published 12/18/2012 01:03 PM | Updated 12/19/2012 07:47 AMBoth Fermi and Kepler GPU generations (GeForce 400, 500 and 600 series) support the Microsoft DirectX 11.1 (DX11.1) API.On future GeForce 600 series boxes, you will see support listed like this: Microsoft DirectX 11.1 API (feature level 11_0).One of the main benefits of the DX11.1 API is that it exposes a lot of capabilities that have existed in our GeForce GPUs since Fermi but were not available in the first revision of DX11.Here is the full list of the new features available in the DX11.1 API: OutputMergerLogicOp UAVOnlyRenderingForcedSampleCount DiscardAPIsSeenByDriver FlagsForUpdateAndCopySeenByDriver ClearView CopyWithOverlap ConstantBufferPartialUpdate ConstantBufferOffsetting MapNoOverwriteOnDynamicConstantBuffer MapNoOverwriteOnDynamicBufferSRV MultisampleRTVWithForcedSampleCountOne SAD4ShaderInstructions ExtendedDoublesShaderInstructions ExtendedResourceSharing UAVs in the vertex, geometry and tessellation shaders UAVOnlyRenderingForcedSampleCount supports 16x raster coverage sampling TIR - aliased color-only rendering with up to 16x raster coverage samplingThese features are exposed through various "hardware feature levels" each of which has a set of required and optional features for that level. Most features have been exposed as added optional features available at feature level 11_0 and 11_1.The last three features : UAVs in the vertex, geometry and tessellation shaders UAVOnlyRenderingForcedSampleCount supports 16x raster coverage sampling TIR - aliased color-only rendering with up to 16x raster coverage samplingare only exposed through the hardware feature level 11_1, as a group of three features:See http://msdn.microsoft.com/en-us/library/windows/desktop/hh404457%28v=vs.85%29.aspx for more information.Fermi and Kepler GPUs do not support two of these features: UAVOnlyRenderingForcedSampleCount supports 16x raster coverage samplingTIR - aliased color-only rendering with up to 16x raster coverage samplingThese two features are intended as path rendering acceleration aids for Direct2D, used optionally if the hardware supports feature level 11_1. We felt that for Fermi and Kepler, it was more important to maximize our investment in work that is more important to 3D graphics and therefore chose not to implement support for those two features.The third feature…· UAVs in the vertex, geometry and tessellation shadersis supported by Fermi and Kepler GPUs however because this is only exposed through the hardware feature level 11_1, as a group of three features, we currently do not support it via the DX11.1 interfaces. We may expose support for the UAVs in the vertex, geometry and tessellation shaders feature on an app-specific basis in the future.We look forward to working with game developers to expose the new 3D graphics features and help take PC gaming to the next level of visual fidelity.
