Theres deminishing returns (visual improvements) on increaseing resolutions.
(720p vs 1080 is a bigger differnce than say 1440p vs 2160p)
Its like that picture with triangle counts, where at start a small increase resulted in a massive differnce in IQ, but lateron massive triangle counts barely improve things.
Hope we spend the GPU resources better than just chaseing resolutions needlessly in the future.
Like I dont see any point in 8k next gen or the one after.
