# Resolution Optimization Setting

Have you experienced PC performance issues when setting the output resolution to 1080p in PRISM Lens? To address this, we have introduced the Resolution Optimization feature. 

This allows you to balance system performance and image clarity by adjusting the internal processing resolution while maintaining your desired output resolution.

#### 1. Accessing the Settings

The previous 'Effect Quality Settings' has been replaced with the more intuitive Resolution Optimization menu.

* To access this feature, click the Settings (gear icon) at the bottom left of the PRISM Lens app and navigate to the Output Settings tab.

#### 2. Choosing Your Optimization Level

You can customize the optimization level for each Lens (PRISM Lens 1, 2, and 3) independently to suit your specific needs.

Select one of the following three options based on your PC's capabilities:

* High Quality – Process at original resolution (Default): Maintains the original high definition. Use this if you have a high-spec PC and want the sharpest possible image quality.
* Balanced (Recommended) – Balance quality and performance: Maintains a high visual standard while noticeably reducing the load on your PC. This is the recommended setting for most streaming environments.
* Performance – Prioritize performance: Maximizes system resource savings by lowering the internal processing resolution. Choose this if you need to ensure a stable, lag-free broadcast on a lower-spec PC.

#### 3. Key Considerations

* Internal Processing: These settings lower the *internal* processing resolution while keeping the *final* output resolution at your selected level (e.g., 1080p).
* Image Clarity: Please note that using Balanced or Performance modes may result in a slight decrease in image sharpness compared to the High Quality setting.
* PC Load: Applying these optimizations provides a measurable reduction in CPU and GPU usage, helping to prevent dropped frames during your live stream.

#### 4. Cases Where Resolution Optimization Does Not Apply

{% hint style="warning" %}
Depending on the platform and the combination of active effects, Resolution Optimization settings may not take effect. In these cases, rendering is automatically handled at High Quality size.
{% endhint %}

**Windows**

Resolution Optimization has limited effect in the following cases:

* Virtual Background is the only active effect (including video or image backgrounds, with no other effects enabled)
* Virtual Background is active along with effects applied later in the processing pipeline (e.g., Mosaic, Color Correction, Color LUT, select effects within Advanced Camera Settings)

Cause: Virtual Background follows a UX behavior that requires the video to fill the output frame based on the output resolution, regardless of input or output orientation. To preserve this behavior, the internal processing resolution may not scale down proportionally in Balanced or Performance mode, which limits the load reduction effect of Resolution Optimization.

**Mac**

Resolution Optimization does not apply or has limited effect in the following cases:

* No effects are active (camera capture only): Frames are processed via a direct rendering path, and Resolution Optimization does not participate in internal scaling.
* Only one of the following lightweight effects is active, without combining any additional effects: Internal processing may remain close to High Quality, resulting in minimal difference between optimization levels.
  * Virtual Background, Motion Blur, Color Correction, Mirror, Rotate, Watermark (including Filter Watermark), Color LUT
* Virtual Background is actively participating in compositing (e.g., video or image backgrounds requiring alignment to output resolution): Similar to Windows, output frame fill and compositing consistency take priority, which limits the load reduction effect of Resolution Optimization.

#### 5. Cases Where Resolution Optimization Is More Effective

**Windows**

* All effects are turned off: Only camera capture output is active, and the internal scaling strategy adjusts dynamically based on the selected optimization level.
* Face Style, Makeup, or Face Shaping effects are primarily active: In pipelines that do not require Virtual Background to fill the output frame, switching to Balanced or Performance mode can provide a measurable reduction in GPU and CPU load compared to High Quality.

**Mac**

* Multiple effects are active simultaneously, or face and beauty effects are used in combination with effects beyond a single lightweight effect: The difference in internal processing resolution between optimization levels becomes more apparent, and the tradeoff between system load and image clarity is more noticeable.
