Remarks

Texture format support varies depending on driver, hardware, and usage flags. In general, you should use SDL_GPUTextureSupportsFormat to query if a format is supported before using it. However, there are a few guaranteed formats.

FIXME: Check universal support for 32-bit component formats FIXME: Check universal support for SIMULTANEOUS_READ_WRITE

For SAMPLER usage, the following formats are universally supported:

• R8G8B8A8_UNORM
• B8G8R8A8_UNORM
• R8_UNORM
• R8_SNORM
• R8G8_UNORM
• R8G8_SNORM
• R8G8B8A8_SNORM
• R16_FLOAT
• R16G16_FLOAT
• R16G16B16A16_FLOAT
• R32_FLOAT
• R32G32_FLOAT
• R32G32B32A32_FLOAT
• R11G11B10_UFLOAT
• R8G8B8A8_UNORM_SRGB
• B8G8R8A8_UNORM_SRGB
• D16_UNORM

For COLOR_TARGET usage, the following formats are universally supported:

• R8G8B8A8_UNORM
• B8G8R8A8_UNORM
• R8_UNORM
• R16_FLOAT
• R16G16_FLOAT
• R16G16B16A16_FLOAT
• R32_FLOAT
• R32G32_FLOAT
• R32G32B32A32_FLOAT
• R8_UINT
• R8G8_UINT
• R8G8B8A8_UINT
• R16_UINT
• R16G16_UINT
• R16G16B16A16_UINT
• R8_INT
• R8G8_INT
• R8G8B8A8_INT
• R16_INT
• R16G16_INT
• R16G16B16A16_INT
• R8G8B8A8_UNORM_SRGB
• B8G8R8A8_UNORM_SRGB

For STORAGE usages, the following formats are universally supported:

• R8G8B8A8_UNORM
• R8G8B8A8_SNORM
• R16G16B16A16_FLOAT
• R32_FLOAT
• R32G32_FLOAT
• R32G32B32A32_FLOAT
• R8G8B8A8_UINT
• R16G16B16A16_UINT
• R8G8B8A8_INT
• R16G16B16A16_INT

For DEPTH_STENCIL_TARGET usage, the following formats are universally supported:

• D16_UNORM
• Either (but not necessarily both!) D24_UNORM or D32_SFLOAT
• Either (but not necessarily both!) D24_UNORM_S8_UINT or D32_SFLOAT_S8_UINT

Unless D16_UNORM is sufficient for your purposes, always check which of D24/D32 is supported before creating a depth-stencil texture!

Version

This enum is available since SDL 3.1.3
