technology supports a wide range of 3D graphics accelerators that can
be upgraded as technology evolves. VRSG
uses the Microsoft DirectX Application Programmers Interface (API), which is a very thin and efficient layer above the rendering hardware.
The graphics API of choice in the game community is Microsoft
DirectX, which in turn receives the largest support by hardware
vendors of any competing graphics standards. The VRSG application is
written with the DirectX API to take advantage of the largest possible
base of potential 3D graphics accelerators. The DirectX API issues a
major release each year with some vendors providing direct hardware
support for some of the DirectX components (such as DirectSound and
DirectSound3D). MetaVR uses only non-proprietary 3D graphics accelerators
that are commercially available from your local computer retailer. MetaVR
constantly evaluates the latest hardware to determine the best possible
graphics accelerators for personal computers. The newest generation
graphics cards have integrated 2D and 3D capability and support visual
simulation as well as desktop business graphics.
The NVIDIA GeForce GTX 680-based video card is built on the much anticipated successor to the Fermi architecture. Kepler is not only the world's fastest GPU, but also the world's most power efficient. With the GTX 680 are new technologies that fundamentally improve the smoothness of each frame and the richness of the overall experience.
New features include GPU Boost, which intelligently monitors graphics work load and increases the clock speed whenever possible. The result is that the GPU always performs at its peak and you get the highest framerate possible. Adaptive V-Sync enables vertical synching (V-Sync) only when the frame rate exceeds the refresh rate of the monitor. When the frame rate drops below this rate, V-Sync is automatically disabled, minimizing stuttering. FXAA is a new way of performing antialiasing that's fast, effective, and optimized for modern game engines. FXAA picks out the edges in a frame based on contrast detection. It then smoothes out the aliased edges based on their gradient. All this is a done as a lightweight, post processing shader. Previously, two NVIDIA GPUs were required to support three monitors. NVIDIA Surround now supports one card powering three monitors for simulation (and a forth monitor for email or web browsing). At 5760 x 1080, the expanded field of view fully engages human peripheral vision and provides for the most immersive experience
