Accelerated rendering with temporally interleaved details

A non-transitory computer-readable medium for storing instructions that, when executed by a processor, cause the processor to configure a graphics rendering command stream to implement reduced frame rendering by performing the steps of:

• receiving a first graphics rendering command stream associated with a first frame of graphics data;
• specifying a nominal resolution at which the first frame is to be rendered;
• determining a reduced resolution for the first frame based on configuration information associated with a graphics processing unit, the reduced resolution specifying a first reduced pixel count in a first screen direction and a first non-reduced pixel count in a second screen direction;
• indicating to the graphics processing unit that the first frame is to be rendered at the reduced resolution and then upscaled to the nominal resolution;
• and
• determining, based on the configuration information associated with a graphics processing unit, that an interleaving function for reduced frame rendering is active,
• wherein the first frame is adjacent in time to a second frame that is rendered at a second reduced resolution specifying a second non-reduced pixel count in the first screen direction and a second reduced pixel count in the second screen direction.

A computer system, comprising:

• a graphics processing unit (GPU);
• and
• a memory storing a graphics application and a GPU driver, wherein the GPU driver includes configuration information and is configured to:
• receive a first graphics rendering command stream associated with a first frame of graphics data,
• specify a nominal resolution at which the first frame is to be rendered,
• determine a reduced resolution for the first frame based on configuration information associated with a graphics processing unit, the reduced resolution specifying a first reduced pixel count in a first screen direction and a first non-reduced pixel count in a second screen direction,
• indicate to the graphics processing unit that the first frame is to be rendered at the reduced resolution and then upscaled to the nominal resolution;
• and
• determine, based on the configuration information associated with a graphics processing unit, that an interleaving function for reduced frame rendering is active,
• wherein the first frame is adjacent in time to a second frame that is rendered at a second reduced resolution specifying a second non-reduced pixel count in the first screen direction and a second reduced pixel count in the second screen direction.
