Razer's Arctosa keyboard driver version 1.01 is available for download from Softpedia. The notes accompanying this release include only Windows 8 support
The manufacturer advises that the device must be plugged in before you start the driver installation.

On its feature list, there’s mention of the 1000Hz Ultrapolling/1ms response time, which really makes a difference in terms of response time.
Below is the link to the driver. Download, install and stay “updated one minute ago.”
