Multipatch features may be very expensive to render, especially if they contain textures (or imagery) draped on their geometry. If you are experiencing poor performance in ArcScene with textured multipatches, try the following:
- Turn on DXT compression.
- DXT compression will compress the texture image for optimum use with your graphics card. There will be a small drop in the texture resolution.
- You can access the DXT compression setting by right-clicking the multipatch layer in the table of contents, clicking Properties, then activating the Rendering tab in ArcScene. Check the Enable rendering with compressed textures check box.
- Increase the virtual memory size to at least twice the size of the physical memory.
- Virtual memory is used when your system runs out of physical memory. There must be enough virtual memory available to handle any data usage overflow from ArcScene.
- You can access your virtual memory settings on the My Computer > Properties > Advanced tab.
- Disable or downscale the textures.
- Often it is the textures stored on 3D multipatch features that are using many of the available system resources. Disabling or downscaling the textures will free up more system resources and improve the interactive performance of the 3D view.
- Disable or downscale the textures by right-clicking the multipatch layer in the table of contents, clicking Properties, then activating the Rendering tab in ArcScene.
- Use a machine with larger physical memory and texture memory on the graphics card.
- Physical memory (RAM) is particularly important, as is the memory and OpenGL support on the graphics card.
- See FAQs for selecting graphics cards if you are considering upgrading your graphics card. This includes how to get updated drivers for your graphics card if it otherwise meets the requirements but you are still experiencing display issues.
