14 DAY TRIAL // NVIDIA has just released version 326.77 beta of their OpenGL 4.4 and GLSL 4.40 drivers. It requires a Fermi or Kepler based GPU in order to get full functionality.
The supported graphics adapters are mentioned in the driver description at the link below. They are Quadro and GeForce 700, 600, 500 and 400 series cards.
OS support is not an issue. This release works on Windows XP, Vista, 7 or 8 on both 32- and 63-bit architectures. There is a separate link for the notebook version of the update, but that will not support Windows XP.
NVIDIA advises users that encounter bugs or issues with this driver to file a report on their developer site. This will help make future releases better.
Below is the link to the drivers. Select the one that will work with your operating system, download it and stay “updated one minute ago.”
