Question 144FPS 144Hz but not smooth gameplay and screen stuttering

[JutsuFn]

please guys can you help me with my problem
I'm actually playing Fortnite with a constant 144 fps but it just feels unsmooth like if I'm playing with less than 60fps. My monitor is Benq XL2411P 144hz and I've been playing Fortnite smoothly for 1 year without problems.Fps shows 144 and Hz is also 144 in nvcp and display settings but the game is choppy and I notice some minor screen tearing. Vsync helped a bit but I can't play with that input lag as a competitive player.
I tried so many things like RTSS, reinstalling driver using DDU,reinstalling the game,format,fresh install of windows but nothing helped.
Please if anyone knows how to solve this problem don't mind helping me because it's really driving me crazy.
My specs:
Mobo: Msi H310M PRO-VD PLUS Intel® Core™ i5-9400F CPU @ 2.90GHz(3.9GHz in task manager while playing)NVIDIA GeForce RTX 2060 16 GB DDR4 2400Mhz 1T HDD 240 SSD 550W corsair PSU
I also noticed that when playing 60hz 60fps capped I get a lot of screen tearing
I think it could be a hardware problem but what exactly is causing this,is it my cheap mobo or maybe PSU?
I'd appreciate every single suggestion.Thanks

Turn FPS limiter to 141 FPS, in game.

That is all you need to do.

BECAUSE you have 144 Hz limit set, you get tearing because this disables FreeSync/GSync. You need to have 3 FPS lower framerate than monitor refresh rate limit for G-Sync(Nvidia), and 1 FPS below the nominal refresh rate of the monitor is enough for FreeSync(AMD GPU).

He doesn't have a gsync/freesync monitor.

exactly

You may also want to try to just remove the frame rate limit altogether and let the game run as fast as it can. This will still have tearing but it should be less noticeable and will give the least input lag.
