Octane Render (Standalone)

Octane Render is a GPU-accelerated, physically-based render engine that excels in delivering photorealistic renders at incredible speeds. Leveraging NVIDIA RTX acceleration can significantly enhance rendering performance by utilizing RT cores for real-time ray tracing and CUDA cores for overall speed improvements.

How to Enable GPU and RTX Acceleration in Octane Render

1. Launch Octane Render
   Open the application from its default path:
   C:\Program Files\OTOY\OctaneRender\octane.exe

2. Activate GPU Rendering

   • Go to File > Preferences.

   • Select the Devices tab.

   • Ensure that all NVIDIA GPUs are selected for rendering.

3. Enable RTX Acceleration

   • In the same Devices menu, find the RTX Backend option.

   • Check the box for Use RTX acceleration to enable ray-tracing hardware for faster render times.

These settings allow Octane to fully utilize NVIDIA RTX technology for optimized rendering.

Top Tips to Speed Up Octane Render

1. Optimize GPU Usage
   Ensure that multiple GPUs are being utilized effectively by enabling multi-GPU setups. Octane performs well with multiple NVIDIA GPUs—especially the RTX series—and scales well across them, ensuring faster render times for complex scenes.

2. Manage Memory and Resources
   For large projects, Octane allows for out-of-core rendering, which uses system RAM if GPU VRAM is exhausted. However, it is recommended to keep projects within the available VRAM as much as possible to avoid performance bottlenecks.

3. Adjust Sampling and Render Settings
   Lowering sampling rates during test renders can drastically reduce render times without significantly affecting visual quality. Use adaptive sampling to focus resources on areas of the image that need more detail.

4. Update Drivers and Software
   Always use the latest NVIDIA Studio drivers for optimized performance with CUDA and RTX cores. Regular updates from both NVIDIA and OTOY introduce performance improvements and bug fixes tailored for GPU-accelerated rendering.
