Game looks smoother even when running at same framerate at lower resolutions

[melibond]

Hi, i play games on my Asus PG279Q at 2560x1440p 165hz.
I play CSGO at 1440p max settings (with my Gtx 980 ti and i7 4770k 4.8ghz so fps is not a problem).
The game runs very smoothly at 165hz and 165fps+.
But for some reason, when i go down to 1080p (even though the framerate was already higher than 165hz on 1440p) the game feels a bit more responsive.
I don't understand why this would be happening when framerates on both resolutions exceed the refresh rate number.

The answers i am looking for is:
1. Is there a way i can make the game at 1440p feel as responsive as 1080p by fixing something.
2. What could cause the problem, and does more pixels just simply make the game less responsive despite of the fps being above the needed range ?

Thank you in advance!

What's your in-game settings?

Speculating in beforehand.

It's possible that what's happening is that 1080 is easier for your PC to handle. You could be pushing lower minimum frames at 1440, or more frequent FPS drops, so that even if you're above the refresh rate, you still notice microstuttering, which is the results of the frame timings (latency of frames) are all over the place. This is why VSync exists, because if the GPU and monitor aren't in sync, then you get stuttering and screen tearing. Later, FreeSync and GSync showed up as better options.

Nice thinking but unfortunately i never get framedrops and i use gsync all of the time (and yes i've tested it without gsync too).
And as for the fps drop, i've never seen it go even below 200 without gsync and i've never seen it move even one bit when gsync is on (going at 165fps).

Thanks for the answer though, that was good thinking.

Nontheless, all the settings are always maxed out, although i've tried messing with the settings quite a lot so, idk if there is anything on the settings that could help.

Anti aliasing, maybe that's on?

Read what i said.
That's not a reply i would consider helpful.

Probably frame timings, which you can't measure unless you spend 5k usd on equipment.

Could be :/
