The first impression was very good, the standard scene was rendered in no time, the viewport is responsive, the materials looking good in the preview and I love the green dots on the dails panel. I linked my runtimes and loaded a scene i made last weekend in Poser pro 11.3. The first render was pretty quick and it looked very well, almost no grain and soft shadows. Only the glossy and blinn channels seems completely gone. Now i wanted to play a bit with the render settings and soon a firework of crashes began. I closed and restarted the program several times, but it wouldn't work. It refuses to open the render settings tab and went down. My resume for the first flight, the rendering is much faster and looks better, some adjustments are needed on the materials. The crashes are annoying, the program is not stable enough to replace the PP11. The start was good, now the fine tuning needs to be done.
