What is NVIDIA GPU Reader?
NVIDIA GPU Reader is a web-based applet that identifies your GPU and finds the latest graphics driver for your GPU.
How does the GPU reader work?
A small Java Applet is downloaded the first time you run the service. This Java Applet only looks at and verifies your system components when you instruct it to do so from the website. This system information is then used to determine the best driver for your GPU.
