Speeding Up Your Renders

When rendering, DAZ Studio takes the raw information from your scene and passes it through your render settings to the 3Delight or OpenGL rendering engines for the final result. Translating all of the 2D and 3D mapping information into individual pixels requires significant computing resources. The actual amount varies by scene complexity: the more items or custom settings and high resolution components you have in your scene (shadows, reflections, high-resolution textures, etc.), the more resources are required and the longer the rendering takes. DAZ Studio is designed to use your computer’s resources as efficiently as possible and we are constantly looking for ways to achieve even greater performance. That said, your scene and your computer are always the largest factors that affect rendering times.

If your render is taking too long for your comfort, there are several things you can do to optimize performance. In order of preference, these steps include:

  • Remove some items from your scene. Lights and multiple shadow settings are particularly costly in terms of required computing resources.
  • Turn off shadows. Shadows require extensive computer resources.
  • Add RAM to your computer. Your computer uses its hard drive as virtual memory, which behaves like additional RAM and expands the total available memory. The only problem with this is that your hard drive is much slower than your regular memory since the computer must read and write data to the hard drive just like any other file. Adding more RAM reduces the need for virtual memory, which can greatly speed up rendering times. The Macintosh platform is particularly responsive to increases in RAM.
  • You should check to see if your computer’s RAM is the best fit for your computer’s specifications. Oftentimes even the large manufacturers put in lower-specification RAM to save money. You may be able to simply replace the RAM you have with higher-specification memory and get noticeable improvements (e.g. replacing PC2100 DDR RAM with PC-2700, or PC-3200 and better if you motherboard supports it.)
  • Upgrade your computer’s CPU if your motherboard can support it. Faster CPUs can process more data in any given amount of time. If your computer has insufficient RAM however, the faster CPU will simply spend more time waiting for information instead of processing the render, which doesn’t do you too much good.
