RSC_RTT_MAIN_DEPTHBUFFER_ATTACHABLE

RSC_TEXTURE_2D_ARRAY 

TEX_TYPE_2D_ARRAY is supported.

RSC_TEXTURE_CUBE_MAP_ARRAY 

TEX_TYPE_CUBE_MAP_ARRAY is supported.

RSC_TEXTURE_GATHER 

Hardware/API supports texture gather operation.

RSC_UAV 

Supports UAVs (OpenGL: SSBOs and Image texture. D3D11: UAVs & structured buffers)

RSC_EXPLICIT_API 

API requires ResourceTransition for everything (e.g.

D3D12, Vulkan, Mantle). Not set for D3D11, and GL. Doesn't mean ResourceTransition aren't required (i.e. GL needs them for UAVs and Compute Shaders)

RSC_SEPARATE_SAMPLERS_FROM_TEXTURES 

Textures and samplers are separate in the shader. OpenGL can't do this.

RSC_MSAA_2D_ARRAY 

Supports doing MSAA on TextureTypes::Type2DArray.

RSC_IS_TILER 

GPU is a tiler, and thus benefits from tight LoadAction & SaveAction semanticsthat avoid loading from & storing contents of what's been drawn from the tiler's cache to RAM.

RSC_TILER_CAN_CLEAR_STENCIL_REGION 

When RSC_IS_TILER is set, this variable being set means the stencil can also be cleared like colour and depth in a tiler-fashion.

Otherwise, stencil is cleared as if GPU were a non-tiler.

RSC_CONST_BUFFER_SLOTS_IN_SHADER 
RSC_TEXTURE_COMPRESSION_ASTC 
RSC_STORE_AND_MULTISAMPLE_RESOLVE 
RSC_DEPTH_CLAMP 
RSC_SHADER_RELAXED_FLOAT 

Shaders supports mediump (aka relaxed precision) and is not masked out due to known bugs.

OpenGL: Disabled, even if supported

D3D11: Masked out due to fxc bugs. See https://shader-playground.timjones.io/3110a80dff6acfbdd8384a64f2fa495d and https://gist.github.com/darksylinc/655495dae603c4e544dd475ae3537621

Vulkan: Supported. May be masked out if driver is buggy

Metal: Unsupported. Use RSC_SHADER_FLOAT16 instead

RSC_SHADER_FLOAT16 

Shaders support float16_t / half datatype as: 

        - Math (i.e. a + b)
        - In/Out blocks (i.e. to pass data between shader stages)

    OpenGL: Disabled, even if supported

    D3D11: Unsupported (needs SM 6.2 / DXC / DX12)

    Vulkan: Supported. Depends on HW GPU support.

    Metal: Always supported.
RSC_UMA 
RSC_PERSTAGECONSTANT 

Is DirectX feature "per stage constants" supported.

RSC_TYPED_UAV_LOADS 

DX11 has this annoying requirement that "typed UAV loads" are not allowed.

Meaning you can only read from UAVs if it's in format PGF_R32_UINT.

You can workaround this issue by creating the UAV as TextureFlags::Reinterpretable and performing bitpacking by hand in the shader.

See https://docs.microsoft.com/en-us/windows/desktop/direct3dhlsl/ dx-graphics-hlsl-unpacking-packing-dxgi-format

RSC_VP_AND_RT_ARRAY_INDEX_FROM_ANY_SHADER 

If capability is not set then only geometry shader can have outputs with SV_RenderTargetArrayIndex and SV_ViewportArrayIndex semantic.

RSC_GL1_5_NOVBO 

Supports OpenGL version 1.5.

RSC_FBO 

Support for Frame Buffer Objects (FBOs)

RSC_FBO_ARB 

Support for Frame Buffer Objects ARB implementation (regular FBO is higher precedence)

RSC_FBO_ATI 

Support for Frame Buffer Objects ATI implementation (ARB FBO is higher precedence)

RSC_PBUFFER 

Support for PBuffer.

RSC_GL1_5_NOHWOCCLUSION 

Support for GL 1.5 but without HW occlusion workaround.
