AMDMemoryOverallocationBehavior (LWJGL 3.2.3 - Vulkan)

java.lang.Object
- org.lwjgl.vulkan.AMDMemoryOverallocationBehavior

```
public final class AMDMemoryOverallocationBehavior
extends java.lang.Object
```
This extension allows controlling whether explicit overallocation beyond the device memory heap sizes (reported by VkPhysicalDeviceMemoryProperties) is allowed or not. Overallocation may lead to performance loss and is not supported for all platforms.
Examples

None.

    VkMemoryOverallocationBehaviorAMD - Specify memory overallocation behavior
    Description
    
    MEMORY_OVERALLOCATION_BEHAVIOR_DEFAULT_AMD lets the implementation decide if overallocation should be allowed.
    
    MEMORY_OVERALLOCATION_BEHAVIOR_ALLOWED_AMD specifies overallocation is allowed if platform permits.
    
    MEMORY_OVERALLOCATION_BEHAVIOR_DISALLOWED_AMD specifies the application is not allowed to allocate device memory beyond the heap sizes reported by VkPhysicalDeviceMemoryProperties. Allocations that are not explicitly made by the application within the scope of the Vulkan instance are not accounted for.
