ERROR_GRAPHICS_UNSWIZZLING_APERTURE_UNAVAILABLE

ERROR_GRAPHICS_UNSWIZZLING_APERTURE_UNAVAILABLE (0xC0262107) means the graphics memory manager had no available unswizzling aperture for the operation. This is a low-level allocation-layout and resource-pressure condition.

What to check

  • For driver or graphics-runtime code, reduce concurrent use of resources that require the aperture and release temporary mappings promptly.
  • Do not assume an allocation can always be converted to the requested memory layout.
  • For user-facing applications, collect the driver version and workload details; this is usually not solved by changing an ordinary desktop setting.
