# Direct GPU Image Sharing

Direct GPU Image Sharing for macOS

Real-time OpenFX signal processing just became ultra-efficient on macOS:

* **Zero-latency GPU image sharing**: The OpenFX plugin now supports **direct GPU memory transfer**, removing costly CPU-GPU copies and enabling **instant signal handoff** to OmniScope.
* **Significantly reduced resource usage**: The plugin has been optimized to use **far less CPU and GPU**, especially when monitoring live Resolve timelines.
* For maximum efficiency, you can also **scale down the input resolution** in the plugin settings, ideal for heavy projects or low-power systems.

### How to enable Direct GPU Sharing

In OpenFX settings, enable "Direct GPU Sharing" option:<br>

Then, after couple of seconds, Nobe OmniScope should auto-detect new **GPU Share Source** named "**NobeOmniScope Metal Output**":

After selecting this source the signal should now be shared directly through GPU with near zero latency.
