NVIDIA Announces Quadro M6000 & Quadro VCA (2015)

by Ryan Smith |
However the company is also pushing the use of Physically Based Rendering (PBR), a compute-intensive rendering solution that uses far more accurate rendering algorithms to accurately model the physical characteristic of a material, in essence properly capturing how light will interact with that material and reflect off of it rather than using a rough approximation.
However as FP64 compute is not widely used in graphics, this is not something NVIDIA believes will be an issue.

Nvidia releases Geforce 340.52 WHQL graphics driver

by Slobodan Simic |
The biggest update for the Nvidia Geforce 340.52 WHQL graphics driver is the support for Nvidia GameStream technology for the new Shield tablet as well as the Shield portable hand-held gaming console.
As expected, Nvidia has now released the new Geforce 340.52 WHQL-certified graphics driver which is a "game ready" driver for a couple of games, has some new SLI and 3D Vision profiles and brings support for GameStream technology for the recently launched Nvidia Shield tablet.

NVIDIA GPUs pre-Fermi Are End of Life After 340.xx Drivers
