Gr\u00e2ce \u00e0 son pilote 436.02, NVIDIA introduit deux fonctionnalit\u00e9s notables. La premi\u00e8re concerne un mode ultra-faible latence<\/a>. La seconde porte sur l\u2019integer scaling<\/em>, un proc\u00e9d\u00e9 de mise \u00e0 l\u2019\u00e9chelle par nombres entiers. Une m\u00e9thode impl\u00e9ment\u00e9e par Intel pour ses IGP Gen11. Contrairement aux approches bilin\u00e9aire ou bicubique, l\u2019algorithme permet d\u2019augmenter la r\u00e9solution sans d\u00e9naturer les couleurs ni alt\u00e9rer la nettet\u00e9 des images.<\/p>\n\n\n\n

Limit\u00e9 \u00e0 quelques cartes<\/h2>\n\n\n\n

Par cons\u00e9quent, l\u2019integer scaling<\/em> se r\u00e9v\u00e8le particuli\u00e8rement attrayant pour les jeux style r\u00e9tro tels que Hotline Miami ou Terraria, ainsi que pour les \u00e9mulateurs. Gr\u00e2ce \u00e0 la mise \u00e0 l\u2019\u00e9chelle des entiers, la r\u00e9solution des jeux augmentent, sans pour autant sacrifier leur cachet. Le GPU se charge de l\u2019op\u00e9ration, en dupliquant les pixels via le plus grand nombre entier possible. <\/p>\n\n\n\n

La fonctionnalit\u00e9, en b\u00eata, est disponible depuis le panneau de configuration NVIDIA, dans le menu “ajuster la taille et la position du bureau”. En revanche, les cartes proposant cette mise \u00e0 l\u2019\u00e9chelle se limitent aux mod\u00e8les Turing, soit les s\u00e9ries GeForce GTX 16xx et GeForce RTX 20xx. <\/p>\n","protected":false},"excerpt":{"rendered":"
