CUE 1.x seems way better. It uses half the RAM - but still too much. 70MB? CUE2 uses 150MB? Roccats App uses only 4MB.
CUE2 does not recognize the Keyboard after update. Profiles do not save.
I just wish a slim, not overcomplicated tool to set the keys once. Since the Keyboard is the only periphery device from Corsair, I do not need any support for other devices integrated in the CUE driver for my keyboard. Make them optional and keep the software RAM friendly.
