of course resolution is king and I really don’t want to get into a massive debate over this. When you go from 1080 to 4K, the game changes entirely. Now one person in the argument is pushing this idea that the brain or eyes can only process 1080 anyway. If this science is true then whatever but it doesn’t really say much if I can tell the difference between 1080 and 4K. I’m of the opinion that resolution makes the game play miles better than playing on a console with really poorly optomised hardware. I made the point that console companies like Sony, Nintendo and Xbox stayed with standard HD for the consoles only recently. Perhaps you had the option to buy one of their PRO consoles which added maybe 2K or even 1440p, pretty sure ps4 pro can only do 1440p at 60fps. Only recently have consoles made 1080p the standard which is just consumerism in a nutshell. I would really appreciate if 2K was the standard and if everyone had the option to play above 2K from the start (PS4 / XBOX 1 generation). It really makes a difference. I’m more mad at the fact console companies are having people debate that 1080p is obviously better just because they’re accustomed to that resolution but I just think that it’s wrong. Why wouldn’t more pixels = better visuals?
Framerate is more important than resolution. 1440p@144 is the sweet spot right now (@120 or @90 if your computer isn't that good) and is arguably better than 4K@60. You can also get in to shit like color depth and peak brightness, but eh.
But overall more is better. Something insane like 32K@480 would obviously and objectively be way better, but diminishing returns do come in to play.
