I like to play for fun but do like to be somewhat competitive. Currently on a 24" 1080p 60hz setup so my questions are:
Is 60-100fps enough at 4k to have a smooth experience and make use of the 144hz? How much better is gameplay at 120fps and is it preferable to 4k for those who have seen both. How does the image fair on this monitor scaling from 1080p to 4k for more fps or playing at 1440p to make use of the refresh rate.
1920x1080 can be scaled "losslessly" into 3840x2160 by very simple operation:
Integer scaling expands every single pixel of source image to cover 2 by 2 pixels on monitor.
That makes pixels of image look bigger if watched closely, but literally can't cause any softness.
In addition there are better scaling&sharpening techs now allowing to avoid blurry/soft look of image when scaling from say 2560x1440 to 3840x2160.
With consoles using AMD's hardware and FSR having minimal implementation workload and as open standard working on any GPU, it's likely going to be found from about every coming multiplatter game.
Also GPU race in next year joining Intel will be bringing out more complex temporal data using open standard scaling tech.
(multiple images as extra source data using algorithms can do bigger resolution increase with good looking result)
Pretty certain AMD will be also updating FSR, or combine their efforts into one open standard with Intel.
There are also sharpening methods not needing any implementation in game and done later.
AMD has
quite effective one.
Nvidia should have something similar, but can't be sure. (Jensen/Nvidia are crooked as corkscrew)
Openly available Reshade post processing injector can be used to do similar sharpening completely independent from game engine.
Multiplayer game anticheat detections likely don't like such post processing.
Anyway future is bright for having high resolution monitor and playing less demanding and those in which highest FPS doesn't matter games at native resolution, and then using scaling to play GPU heavy but high fps needing games.
