Unfortunately, the latest version of Boot Camp requires the use of a 64-bit version of Windows, so we elected to use the 64-bit version in our virtual machines as well for the sake of consistency.Įach of our Windows 10 virtual machines was configured for maximum performance, with 8 assigned virtual CPUs, 12GB of RAM (the maximum recommended amount in order to ensure that enough is reserved for OS X), and 1GB of graphics memory configured for Fusion 8’s DirectX 10 and OpenGL 3.3 drivers. Regarding our choice to use the 64-bit version of Windows, it’s true that the 32-bit version can be easier to virtualize and therefore may offer slightly better performance in certain circumstances. Our guest operating system for all tests is Windows 10 Pro 64-bit, which was installed separately in three configurations: native to the Mac’s hardware via Boot Camp, in a virtual machine powered by Fusion 7, and in a virtual machine powered by Fusion 8. We’ll revisit El Capitan once it launches later this year and we’ll let you know if it provides any performance boosts that would alter our Fusion 8 benchmark results.

We therefore used OS X Yosemite 10.10.5, the latest publicly available version as of the date of our tests, as our host operating system. Even though Fusion 8 supports OS X El Capitan, we’re reluctant to perform tests on beta software.
