64 Bit Considerations

IRender nXt, will on 32 bit systems. But will work much better on a 64 bit system with at least 4 GB RAM

Speed

Most models will render faster and better on a 64-bit system.

Note: The Video card is not used for rendering in IRender nXt and will not effect rendering speed or performance.

64 bit systems allow you to add more than 4GB of physical memory to a machine-- this will result in performance benefits for all of your apps., including 32 bit ones.

Model Size

64 bit systems can run much larger data sets (more detailed models-- hi-res renderings, etc.). They are not subject to the 2GB per-process address space problem. This problem is so significant in the SketchUp, AutoCAD and Rhino worlds that we wouldn't recommend a 32 bit system to anyone looking for a new machine for these purposes. The SketchUp world is more complicated since SketchUp does not have a 64 bit version.

File Locations

Programs, such as SketchUp, which normally install into Program Files on 32 bit systems, install into Program Files (x86) on 32 bit systems. So many references in the documentation which refer to typical installation locations, such as C:\Program Files\Google\Google SketchUp 7\Plugins will be located in a different location on the 64-bit systems. (Usually C:\Program Files (x86)\Google\Google SketchUp 7\Plugins)
