I find the exploration realtime render to be OK to see that the composition and changes you make in real-time are having --or MIGHT have-- the effect you are after, and try out view angles. Sometimes a fast preset is just as good. It never looks as good as your final render, and it doesn’t use the same view and resolution (since it is just responding to the view you have in SketchUp), so it doesn’t guarantee the render will be what you want.
Personally I am “OK” with Twilight speed and use different presets. They’ve added a denoise plugin that looks like it will get you renderings faster–but that would push it over $100.
So it sounds like the question is upgrade Twilight or find a faster renderer that has results as good as Twilight.
