Slow preview in the layout/modelling tab So I am very new to blender and I am currently doing the donut tutorial..I am having an issue. When I try to preview the donut in the shading tab it previews it very quickly but when I do the same in the layout tab it loads very slowly. The viewport is set to 32. I have a 1050ti and the render engine is set to Cycles. Any help will be appreciated
The reason the scene is rendering faster in the Shading Tab is because by default, the 3D  viewport in that tab is less than half the size of the 3D viewport in the Layout tab.
Very simply put - The scene renders faster in the shading tab (in your example) because the viewport is smaller, and therefore there are less pixels to render overall.
