Layer Processing speed of 2.1.beta is much much  slower than in 15.04.05.\r\n2. In 15.04.05 during layer processing the portion of the object which has already been processed gets displayed. In 2.1.beta the platform stays empty until processing was finished by100%.\r\n3. After processing was finished stepping through the layers with Ctrl+Arrow-Keys happens nearly instantuous and seamless in 15.04.05. But in 2.1. beta there is an extreme delay every time you are stepping from one layer to the next one (rolling arrow bisede the layer scrollbar & layer number indicator)\r\n\r\nLayer display is really essential for me.\r\nAlthough I like many of the new features of 2.1.beta for me this extreme degaradation in layer processing/displaying performace  really is a no go.\r\nThis makes working absolutly impossible.\r\n\r\nSo I returned to 15.04.05.\r\n\r\nInfo:\r\nUltimaker 2+\r\nIntel i5-4210U\r\nGeForce 840M\r\n"}}
