Abstract
The introduction of an “out-of-memory” marker in the sorted tile geometry sequence for a tile may aid in handling out-of-memory frames. This marker allows hardware to continue rendering using the original data stream instead of the sorted data stream. This enables use of the original data stream allows the system to continue rendering without requiring any driver intervention. During the visibility generation/sorting phase, the number of memory pages required for storing the data for a rendering pass is continuously tracked. This tracking includes tracking the pages that are required even if the hardware had not run out-of-memory. This information can be monitored by a graphics driver and the driver can provide more memory pages for the system to work at full efficiency.
