Skatter is indispensable, I signed up to the earliest possible preview years ago and still use it all the time. It won't be as fast as Twinmotion, or even Forest pack, but it does exactly what it says it does, is quite flexible and is very reliable.
I should add, I am running a dual xeon/RTX3090/256gb RAM 2 x TB SSD machine (though I suspect the advantage of such a machine is limited with SketchUp), so can't say what the results will be on something more consumer-grade.
lol, with a 3090 and your pc configs you can scatter all EARTH PLANE (lol) .
congrats for your machine
