gpuViewer is a photo viewer that makes use of the GPU on your graphics card and the multiple cores in your processor to speed up the interface and let you review your library faster. Drawing on technology and methods used in video-games engines, gpuViewer is about smooth interaction and a quick feedback loop. In october 2006, tired of waiting in front of €œloading € or €œrefining € signs, I felt modern hardware should be able to do a faster job at displaying photos than what was available. When people asked €œwhat €™s the best graphics card to use with Photoshop? €, the quick answer used to be €œdoesn €™t matter: it doesn €™t use advanced features of graphics cards €, how crazy is that? When Aperture came out, I thought times were changing and that GPU (Graphics Processing Units) would become the norm almost overnight. But not. Products like Lightroom still mostly use good old techniques and, when working with large files, it shows.
