Microsoft’s Windows Mixed Reality headsets recently started shipping to developers, but they won’t really feel complete until people can get their hands on the accompanying motion controllers, which go on sale this holiday. Microsoft first revealed these controllers in May, and we finally got to check them out a little bit last week, in advance of a public appearance at the IFA electronics show. They’re not the most elegant hardware, but they’re an impressive technical achievement: a pair of full-featured motion controllers that work without any fixed external trackers, just cameras on the VR headset itself.

Like the headsets, Windows Mixed Reality controllers will be released by Microsoft partners, including HP, Lenovo, Dell, and Acer; bundles of the two will start at $399. (While “mixed reality” refers to a spectrum of immersive technology, Microsoft’s Mixed Reality headsets are basically just VR headsets.) Microsoft developers are supposed to always plug their headsets into comparatively high-end PCs with dedicated graphics cards, but for consumers, there are two options. The “Windows Mixed Reality Ultra” baseline has a graphics card, and experiences will run at 90 frames per second, the optimal standard for VR. “Windows Mixed Reality” PCs have integrated graphics, and run at 60 frames per second, a minimum standard.
