Claim:
1. Apparatus for processing graphics primitives for display comprising: rasterization circuitry to generate graphics fragments corresponding to the graphics primitives; obscuration identification circuitry to receive the graphics fragments from the rasterization circuitry and to identify an obscuration condition when allowing a first received graphics fragment to be processed for display and allowing at least one previously received graphics fragment to be processed for display will result in at least one further previously received graphics fragment being obscured even when the first received graphics fragment and the at least one previously received graphics fragment do not share a boundary; and process killing circuitry to prevent further processing occurring with respect to the at least one further previously received graphics fragment when the obscuration identification circuitry identifies the obscuration condition, wherein the obscuration identification circuitry is responsive to reception of a next received graphics fragment to identify the obscuration condition when allowing the next received graphics fragment to be processed for display and allowing the first received fragment to be processed for display will result in the at least one further previously received graphics fragment being obscured even when the next received graphics fragment and the at least one previously received graphics fragment do not share a boundary, wherein each of the first received graphics fragment and the at least one previously received graphics fragment would not individually result in the at least one further previously received graphics fragment being obscured.
