All of the major (and some of the minor) gaming-gear manufacturers have developed their own mouse-control customization software, which usually encompasses advanced macro programming. Often, the software also enables you to control and customize a gaming keyboard of the same brand. In addition to recording macro commands, these software dashboards let you activate premade, game-specific profiles; create your own profiles; and adjust any on-mouse lighting/LED bling. Many also offer presets for non-gaming use, letting you leverage your mouse's programmability in Excel or Photoshop when you're not blowing up starships or hapless zombies.
While a lot of people might be bummed out to know about the downgrade, you actually shouldn’t pay attention to it. The reason is simple, while the Sabre RGB is certainly the cheaper option, a lower price, and a different design gives it an identity of its own, and that is certainly a good thing because, at the given price point, you are getting a mouse that is able to have an impressive 10,000 DPI, a good design that will attract most gamers, and not mention, RGB lighting. So, in simple words, gamers are paying less and getting more when it comes to the Corsair Sabre RGB.
