# RHIDevice::GetCapabilities

```cpp
virtual const RHICapabilities& GetCapabilities() const = 0;
```

获取当前设备的图形能力。

**返回：** 设备能力结构体引用

**复杂度：** O(1)

**示例：**

```cpp
const RHICapabilities& caps = device->GetCapabilities();

if (caps.bSupportsRayTracing) {
    // 启用光线追踪功能
}

if (caps.bSupportsComputeShaders) {
    // 启用计算着色器
}

uint32_t maxTexSize = caps.maxTexture2DSize;
```
