Understanding graphics cards Kathmandu Post Nepal, July 13 -- Video game graphics have gotten more complicated over the years. Games look more and more photo-realistic these days and with added lighting, geometry and anti-aliasing techniques; these games demand a lot out of your systems. In days of yore, all the graphical elements your computer produced would be handled by the CPU itself, in what was called 'Frame Buffers', but these days, because of the complexity of modern graphics, a dedicated Graphical Processing Unit (GPU) is assigned the task of all graphical rendering on screen, and these include your operating system's graphics as well as your hardware accelerated programs. While not only used to render games, graphics cards are also important for a plethora of other applications. For one, these GPUs are extremely useful in cryptocurrency mining. They are also essential in any system used for creative work like graphic design, video editing and 3D modelling. Almost all Adobe Creative Cloud applications support GPU hardware acceleration and work best when paired with a dedicated graphics card.
