#3d vision controller drivers
You can download the latest Nvidia drivers from the official website. I suggest - highly - that you also check the perform a clean installation option unless you have created profiles that you want to retain. I disable all features but PhysX during installation to avoid installing drivers that I do not need on my system. It checks online to find new drivers, can optimize games so that they run better on your PC, and video broadcasting options. NVIDIA GeForce Experience - This tool serves several purposes.If you never play games, you do not need this. PhysX System Software - If you are into gaming, you may need to install this for some games to run.If you check for updates manually all the time, you do not need the process running in the background on your system. NVIDIA Update (no longer offered) - This resident program checks regularly with NVIDIA if driver updates are available.

If you don't, you do not need to install this driver either.
