1Apps can create resources bigger than the maximum resource size on some graphics hardware. However, we recommend that apps keep resources smaller than the maximum resource size to get the maximum amount of compatibility across graphics vendors. The runtime only guarantees that allocations within the maximum resource size are supported by all Direct3D 10 hardware. If an app tries to allocate memory for a resource within the maximum resource size, the runtime fails the attempt only if the operating system runs out of resources. If an app tries to allocate memory for a resource above the maximum resource size, the runtime can fail the attempt because either the operating system is overextended or the hardware does not support allocations above the maximum resource size.
