Claim 0:
1. A method of rendering, in a rendering space, a scene formed by primitives in a graphics processing system, the method comprising:
a geometry processing phase, comprising the step of:
storing fragment shading rate data representing a first fragment shading rate value and associating data identifying a primitive with the fragment shading rate data; and

a rendering phase comprising the steps of:
retrieving the stored fragment shading rate data and associated data identifying the primitive,
obtaining an attachment specifying one or more attachment fragment shading rate values for the rendering space,
processing the primitive to derive primitive fragments to be shaded, and
for each primitive fragment, combining 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.
