FSR2TextureTable

Description

The set of texture slots available for the FSR2Context. SA GraphicsDevice.ExecuteFSR2.

Use this struct to specify input and output textures for the FSR2 implementation.

Note: You must create output color texture colorOutput with enableRandomWrite parameter set to true when initializing the RTHandle of the texture. This is due to FSR2 passes requiring access to the resources in a compute shader

Refer to the Input resources section in FSR2 Documentation for more details.
