Software
The software driver for the Fnatic miniSTREAK and other recent Fnatic peripherals is currently in early access and aptly called Fnatic OP (get it?), and the installer can be downloaded from
this page. The installer is in fact an executable that is ~56 MB in size and, once you give it permission to install, it effectively updates the keyboard firmware if applicable and installs the program without any user controls. I definitely hope the final version adds more control, including the location of the program and whether or not a shortcut should be added, but the final version is fairly lightweight and takes up as much room as the installer itself.
Opening it for the first time with the keyboard connected, we see a homepage that has a list of the compatible products with the miniSTREAK all the way to the left, with an icon corresponding to it also seen below the home icon at the top left. For what is early access, I was very pleasantly surprised to find no bugs and a clean user interface. Fnatic has had software drivers in the past for their earlier products, so this new version definitely builds upon that base and is not just another program starting from scratch.
The settings menu in Fnatic OP does not have a lot going on in the early access state, but you can choose between two languages and whether you want it initiating at OS startup as well. There are also four onboard profiles that can be configured separately, and associated lighting profiles for each by default, which also can be changed as needed. The main product page also has a specific lighting scheme for competition mode, which is one of the extra discrete buttons on the keyboard, and it too can be configured as seen above.
Lighting takes up a lot of real estate here, given we already saw profiles and the competition mode having associated lighting effects, and you can use the software for more granular control over the offered per-key 16.8 M RGB backlighting. There are some preset lighting effects to choose from, each of which has sub-menus for more options, including direction and speed of dynamic effects, selecting groups for per-key lighting with individual R/G/B channels in 256 steps (total of 16.8 million colors), and gradients for static or reactive effects. The other tab is for key mapping, and it too has a few options, including a full remap, macros, starting an application, or opening a web link. Macro recording in built in here and works fine. There remain some options offered by more established peripheral companies that are absent here, but this is a really good start from Fnatic.
