High FPS vs. HQ Graphics - the best balance?

I’ve spent several hours benchmarking Grim Dawn to find the best balance between high-quality graphics and good performance. I’m sharing my results here so hopefully the next person trying to optimize their game will have an easier time discovering what works / what doesn’t. The goal: Grim Dawn is a gorgeous game. We want those beautiful graphics, and want to share them with our viewers: for those who stream/create videos. But we also want good performance; what good are great graphics when all…

i will mention this too, which another AMD user mentioned
