I currently am using a ViewSonic XG-2700-4K on a GTX 1080. However, in some games that I would rather have High settings over Medium settings, I would have to sacrifice the resolution.
I use CRU (Custom Resolution Utility) to have a custom resolution of 3200x1800. However, some people recommend GPU scaling and others Display scaling to improve the image.
What are some of the differences in scaling on the GPU vs on the Display? Would one look better in-game over the other? Are there any other differences besides image quality?
