Triple Buffering: Third buffer for fast graphics display [Hint ]Triple Buffering: Third buffer for fast graphics screen. [Details] There are in fact two buffers on contemporary graphics cards, the Primary Buffer along with the Secondary Buffer, also often referred to as the Front Buffer and the Back Buffer. Both are storage places within the Video RAM of the card, along with the process of using 2 buffers at the same time is known as Double Buffering. It was only comparatively recently that graphics cards needed enough VRAM to provide two buffers at all resolutions, but because one framework of high resolution detailed images can occupy a terrific deal of video memory, much less two of them. The graphics card uses the secondary buffer to automatically compose a new frame while the principal buffer is sending a present completed framework to the screen. When these jobs are done, that the buffers are essentially’flipped’ roughly so that the newly finished frame in the secondary buffer now becomes the key buffer prepared to send to the track, even though a new framework starts composing in what had been the key buffer a second ago. This can be duplicated over and over and therefore the use of two buffers signifies the graphics card is not constantly waiting for a single frame buffer to be removed before getting on with rendering more frames Triple buffering Improve your PC gaming performance for free – GameCritics com to store there. It’s like putting a fire out with two pieces of water instead of simply one – a bucket can be filled with water whereas the contents of the other has been thrown on the fire, and then they are switched and the process repeated; much quicker than simply using a single bucket. There is still a issue with double loading, and that’s when VSync is enabled, the graphics card can often fill both buffers and must then stop working on any new frames until the monitor indicates it is prepared for a new framework for the next refresh. Only after that can the graphics card clear the primary buffer, change buffers and begin rendering the next frame from the secondary buffer. This waiting is the thing that causes a drop in FPS when VSync is enabled on many systems. Wouldn’t it make sense to have more than two buffers? Why not 3 buffers like – that will provide the graphics card more room to render frames without needing to be concerned about where to keep them until they’re sent to the screen, even if VSync is permitted. Well there’s an option which does just that, called Triple Buffering. And it usually does exactly what the name suggests, it produces a third buffer in the VRAM, which people can call the Tertiary buffer. [Reference]Posted From Santhosh G.
