Claim 11:
12. A graphics processing system configured to render, in a rendering space, a scene formed by primitives, the system comprising:
geometry processing logic configured to:
store fragment shading rate data representing a first fragment shading rate value and associating data identifying a primitive with the fragment shading rate data; and

rendering logic configured to:
retrieve the stored fragment shading rate data and associated data identifying the primitive,
obtain an attachment specifying one or more attachment fragment shading rate values for the rendering space,
process the primitive to derive primitive fragments to be shaded, and
for each primitive fragment, combine the first fragment shading rate value for the primitive from which the primitive fragment is derived with an attachment fragment shading rate value from the attachment to produce a resolved combined fragment shading rate value for the respective fragment.
