Good for you!That did the trick, and holy shit is it fast now. The CPU took ten minutes to do what this just did in two. Admittedly simple, but just testing. Let me work on something a bit more elaborite, and I'll post it.
I met the same issues you did (only CPU at first, I then spent a few hard earned bucks on my rig and now I've got a RTX2060 as well) and the difference is breath taking. My best example would be the pictures below that would have taken maybe an hour or so with my old config and now took less than 10 minutes for both
