At native 4K resolution, essentially every non-ray traced game runs at 100 frames per second or higher. Some exceed 144fps as a matter of course, meaning that they'll 'max out' a 144Hz ultra HD display.
Yes yes, I know what you meant! But I am saying, Native res. these days don't matter much.
On a console! Most of the games (almost all Sony 1st parties especially) are providing a solid 60 fps mode these days where IQ looks good too regardless of the 'old standard' of Native numbers.
I didn't even mention the word "native" in my post bhae
Its possible even the 4K30 RT mode is using some form of reconstruction to reach 4K. If not, then the 1440p Performance mode suggests that the output will be straight up upscaled in the old school way and look rather blurry on a 4K display.
But one thing is clear, the consoles are already CPU bottlenecked in RT modes.
