# minimizeMemory

An option that instructs Metal to prioritize building an acceleration structure that needs less memory.

## Declaration

```swift
static var minimizeMemory: MTLAccelerationStructureUsage { get }
```

## Discussion

Discussion The acceleration structures you build with this option can increase their build times and can reduce their intersection performance.
