Viewport rendering

I tried the denoise vieport rendering in 2.83 and my computer was using up to about 22 gb when I only have a total of 20 gb. I had to hit wireframe render to stop the process. Today I put all the objects for my exterior render in my archipack collection, that I can see in the render including interior objects I can see through the windows in the render. I set my computer to optix in preferences and set it to viewport denoising in my render options. I disabled all other collections I don’t need to see in the render. Now that I have isolated my render to the archipack collection, the grove and a couple of rocks, will my computer use less resources to compile the shaders? Thanks
