NVEnc is a CLI (Command-Line Interface) software, meant to investigate performance and image quality of HW encoder (NVENC) of NVIDIA.
NVENC is NVIDIA’s encoder. It’s a physical section of our GPUs that is dedicated to encoding only. This means that your GPU can operate normally regardless of whether you use this region to stream or record.

Other encoders, such as x264 codec, use your CPU to encode, which takes resources away from other programs such as your game. That’s why using NVENC allows you to play games at a higher framerate and avoid stuttering, giving you and your viewers a better experience.
