Nvtray is described as 'NVTray provides some extra quality tweaks that both the default NVIDIA tray icon and control panel are lacking. I especially wanted to be able to select more Antialiasing modes, as well as OpenGL and Direct3D options right from the tray icon' and is an app in the System & Hardware category. There are more than 10 alternatives to Nvtray for a variety of platforms, including Windows, Linux, Android, iPhone and Mono. The best alternative is Open Hardware Monitor, which is both free and Open Source. Other great apps like Nvtray are MSI Afterburner (Free), GeForce Experience (Free), RivaTuner (Free) and ASUS GPU Tweak III (Free).
