Regional adjustment of render rate

A graphics processing unit, comprising:

• an interface to couple the graphics processing unit to a processor,
• a plurality of texture units,
• a shared memory coupled to the plurality of texture units,
• a plurality of register files coupled to the shared memory,
• a plurality of load/store units coupled to the shared memory,
• a plurality of graphics processing cores coupled to the plurality of register files, and
• a non-transitory storage medium comprising instructions that when executed cause at least some of the plurality of graphics processing cores to:
• identify a first region of a display based at least in part on historical information associated with the first region;
• in response to the identification, anti-alias the first region with multi-sampled anti-aliasing, including to render the first region at a first render rate;
• and
• anti-alias a second region of the display with temporal anti-aliasing, including to render the second region at a second render rate less than the first render rate.

A graphics processor, comprising:

• a register file to store information;
• a plurality of arithmetic logic units coupled to the register file;
• a plurality of texture units coupled to the register file;
• and
• a non-transitory storage medium comprising instructions that when executed cause the graphics processor to:
• identify a first region of a display based at least in part on historical information associated with the first region;
• in response to the identification, anti-alias the first region with multi-sampled anti-aliasing, including to render the first region at a first render rate;
• and
• anti-alias a second region of the display with temporal anti-aliasing, including to render the second region at a second render rate less than the first render rate.
