Re: Is EVGA GeForce GTX 680 4GB DDR5 available
EVGA GeForce GTX 680 4GB DDR5 available in Amazon, the GeForce GTX 680 has NVIDIA adaptive V-Sync About each month of the frame rate and screen tearing, does not have some of the more frustrating. Each month of the frame rate will tend to occur if the frame rate is low, the tearing of the screen will tend to occur if the frame rate is high. Adaptive V-Sync is a method of rendering frames smarter. At a higher frame rate, V-sync is enabled to eliminate tearing, is at a lower frame rate, V-sync is disabled in order to minimize each month. Because these give an adaptive way of removing the V-Sync, you can enjoy the game your heart's content. 3D Vision NVIDIA , you can deliver to your PC experience truly immersive stereoscopic 3D. 3DVision a combination of high-tech wireless glasses and advanced software, convert it to a full stereoscopic 3D image hundreds of PC games. 4 Use the four technology 3D LightBoost NVIDIA, trying to get up to twice the brightness of the monitor and keyboard. In addition, you can enjoy crystal clear quality, stunning, 3D movies and 3D digital photos can be obtained from 3DVisionLive.com. In the three monitors, so be nice to play your favorite game is not available. If a wide field of view 5760 x 1080, so that will take full advantage of human peripheral vision, you can experience the best in immersive racing and flight simulator. If the display of the fourth expansion, while playing a game, you can check E-mail and chat, the web.
The GeForce GTX 680 is based on the GK104-chip code-named Kepler, named after the German scientist Johannes Kepler. With the NVIDIA GK104 is the first time in the desktop area on a 28-nm process, which takes place at the AMD competitors already in the middle class and high-end GPUs, the Radeon HD 7000 series use. With the developments of the GK104 loud NVIDIA was particularly low power consumption combined with high-performance 3D gaming in the foreground. Accordingly, there are also some changes to the previous GPU architectures reported. One of the most obvious changes is the standard clock for the entire GPU. NVIDIA separates the GK104 of the higher clock domains (the so-called "hot clock") for the shader units, instead, these computing engines run at the same clock as the rest of the GPU. The lower bar must be compensated by a larger number of CEs per streaming multiprocessors again. The extra processing units may cost extra transistors, however, higher clock rates and associated higher stresses act according to NVIDIA significantly greater impact on power consumption. The entire NVIDIA promises by shifting away from the higher clocked shader units, a better power-game performance ratio.
During MSAA against the clear FXAA sharper and thus provides better picture, it costs significantly more power. With TXAA polygon edges are smoothed only with 2x MSAA, calculated from multiple angles and filtered texture edges using modified FXAA. With this trick, Nvidia wants to achieve, according to his own statements with easy TXAA the image quality of 8x MSAA, but without having to consume much more power than with 2x MSAA. In our testing the GTX 680 may TXAA keep this promise, but only conditionally? Although high-contrast edges visible benefit of TXAA and smoothed at first glance as good or even better than with 8x AA, but the image suffers with TXAA as already FXAA under a slight blur. The new Adaptive VSync. Usually coupled VSync the refresh rate to the build-up rate of the monitor in order to prevent so-called tearing, so ugly horizontal line shifts. By default VSync limits FPS on the 60th if the graphics performance slips below this level, but VSync halved the frame rate. Playing is the extreme variability of the refresh rate with a short jerking, which in the fervor of online battles in the worst case. The Geforce GTX 680 with adaptive smoothing the FPS VSync curve much smoother by avoiding the usual big jumps. If the FPS drop below the mark of 60 frames per second, then the frame rate is reduced, for example, not 30 fps but on actual payments made 50 or 47 fps. The practice test is working properly Adaptive Vsync and leads to a significant subjective soft game play. Nothing has changed hung himself in the anisotropic filter. The works so far as very clean and located on a (very high) level with the competition.
