In a recent email by Futuremark's director of engineering, Jani Joki, we were all given a little clarification as to how Futuremark software will operate with Windows 10.
As it stands, all current Futuremark benchmark programs are compatible with this recent operating system release, however, users are reminded that the latest version of SystemInfo should be installed to make sure. This means that 3DMark, 3dMark 11, 3DMark Vantage and Powermark will work as per usual.
There are a few programs which currently stand on shaky ground compatibility wise. If you're worried about your software, head here to see a comprehensive list and information on compatibility.
