I would like an opinion on the slowness of a render, is it normal for a render of an external project to take 2 hours and 40 minutes with HDRI lighting, 2400 x 1817 resolution, 7% noise limit setting with hight quality filter, all default settings GI with Path Tracing and UHD Cache, the scene has a lot of grass and trees, about 7 million polygons, it's all optimized with textures of 1024 px and about five with 4k, only one displacement, I don't have a missing message memory it renders well, my doubt is about the time to be able to clean the scene, when I put 4% noise limit it goes up to 5 hours and 40 minutes, my desktop has the configuration of I7 5930 K, 32 Ram, Corona 9 updated and 3ds Max 2019, all vegetation created with chaos scatter.
