I have recently been looking for a C++ maths library for use in game development projects. There are plenty of posts on websites like gamedev.stackexchange.com with suggestions for libraries but few quantitative comparisons between them. I decided to take three of the most popular libraries and run some tests of my own. Below I describe the three libraries I’ve compared with their advantages and disadvantages and then show the results of some performance tests.

The code and results are also available on GitHub for testing.
The libraries tested are:
These choices are largely influenced by reading their websites and posts at the Game Development StackExchange site:
