It would be useful to know in general which of the other graphics settings have the most impact on GPU Usage vs. VRAM Usage.
I get that resolution (= DLSS Quality setting) has the biggest effect on both, but for example if I want to make the GPU Processor USAGE higher WITHOUT increasing the VRAM usage, what are the main things?
Do shadows at a higher value still affect the VRAM a lot? What about things like Light Shafts and Raymarched Reflections? Supersampling? Trees etc etc (basically all the options on that page).
Conversely which are the things that mainly increase VRAM without putting more load on the GPU processor?
And I guess, is this the same theory for DX11 and DX12 or do they differ?
I’m trying to make my GPU work harder but without using more VRAM. What should I focus on? Is it possible or do they both really go up together regardless of the settings in the Graphics Options page?
