NASA is using Nvidia graphics cards to develop a more vivid and realistic flight simulator experience.

 
Current simulators offer a 20/40 vision, significantly poorer than the standard 20/20 vision or the 20/13 vision that most young military pilots have when starting their flight careers. This means the images displayed are blurred or difficult to identify, providing for a less effective training routine.
 
NASA's latest simulator, co-developed with the US Air Force Research Labs, provides displayed images at 20/10 vision, which means even those with exceptionally good eyesight will see no blurring for objects twice as far away as the typical viewer.

To manage this feat, NASA is using nine 4K projectors, which have a resolution that is 36 times that of a normal high-definition television, powered by lots of Nvidia Quadro GPUs and Quadro Sync cards, all packed with the largest frame buffer memory available.
 
The result is that the technology has been reduced from the previous requirement of 36 computers to just five computers, while maintaining a frame rate of 60 frames per second while drawing a new scene every 1/60th of a second. The graphics cards handle the warp and bending between the projectors, reducing latency and costs.
 
NASA plans to increase the resolution of the simulator in early 2013 by adding an additional six projectors.
