Abstract
Modification messages may be filtered to reduce the load on a message channel between a render cache and a frame buffer compression. A group of cache lines may be checked to see whether both a subspan request hits an unlit bit and a modify message was already sent. If so, the modification message may be filtered.

A method comprising:
- processing a group of render target cache line modifications;
