Razer
While you can still access Razer Chroma controls via the Razer Synapse app, sometimes it's senseless to use this heavier software just to control your RGB lighting on your Razer devices (and the lights from supported partners). That's why Razer spun out the Razer Chroma into a standalone app. This should be easier for your computer and should run faster. You can access all the controls and options you need here. Razer will have an open beta test for the app later this year.
