The last 3 columns show the buildtimes (total and stages 1 and 2) for [anandtech 2017 CPU tests win10 - photoscan 1.3.3 large](https://www.anandtech.com/bench/CPU). The software uses four stages:
The software uses four stages:
- Align Photos
- Align Photos (CPU)
- Build Dense Cloud
- Build Dense Cloud (CPU, GPU)
- Build Mesh
- Build Mesh (CPU)
- Build Texture
- Build Texture (CPU)
Of these four steps, only the "Build Dense Cloud" step is able to utilize the video card. However, that one step takes longer than all the others combined so it makes choosing the correct GPU for PhotoScan critical to ensuring that the hardware in your system is correctly optimized.

It might be worthwile to test operating system dependent performance (Linux, macOS, Windows) with a reference scene from the project. Some users reported using Linux yields maximum performance. One user reported that the processing time for the step `Build Dense Cloud` was cut in half while using Linux instead of Windows.
To further reduce the processing time, Agisoft PhotoScan can be configured to run on a computer cluster where processing is distributed on several computer nodes connected to a local network. See [Manual Chapter 8](http://www.agisoft.com/downloads/user-manuals/). This may need multiple licenses.
