Issue 6. Navigation of Viewport is Slow/UI is Unresponsive

Problem:

Known issue with display refresh time out on Windows.

Solution:

This can be attributed to a function that is included in some operating systems that shut down any program after the OS has lost communication with the GPUThe GPU is responsible for displaying graphical elements on a computer display. The GPU plays a key role in the Octane rendering process as the CUDA cores are utilized during the rendering process.. Since higher resolutions and Path Tracing both can take long periods of time to render a single frame, the OS loses contact with the GPU and shuts down Octane.

This can be resolved one of two ways:

• Purchase a second GPU and dedicate one to OctaneRender™ and one to the operating system.
• Adjust the time out values specific to the operating system. As this typically involves adjusting critical OS files, it is not recommended and not supported by the OctaneRender™ Team. For Microsoft Windows systems, more information can be read here.

Problem:

Render card has insufficient performance.

Solution:

We suggest purchasing a more powerful GPU be purchased to get the most out of OctaneRender. For benchmarks on how GPUs perform with OctaneRender, check the OctaneBench scores here: https://render.otoy.com/octanebench/results.php?v=3.06.2&sort_by=avg&filter=&singleGPU=1

Problem:

Navigating is slow. Is there anything else I can do?

Solution:

To increase the speed of navigating in OctaneRender^®, you can:

• Use the Shift key while rotating, moving, or translating the Render Viewport.
• Use the Sub-Sampling settings (3 checkerboard icons in the viewport) to increase the speed of navigating in the viewport.
• Reduce the Render resolution of the Viewport while setting up materials, lights and camera.
