[SOLVED] Games feel laggy with high fps

[flomor]

Hello everyone, I recently upgraded my pc and I've changed everything except gpu, hd and case. Since then when I play fortnite it feels like I'm playing on 30fps but I've locked them on 144 and they are stable. But sometimes the game is smooth fo a while and then it starts to doesn't feel smooth. I tried other games like overwatch and apex legends and I had the same issue. If anybody could help me I would be greatfull. I have two monitors, the first 144hz monitor (asus 248qe), the second 60hz (asus 278q).
I thought that it could be that the gpu can't handle both monitors because when I set the hz at 120 on my primary monitor the games feel much better. The two monitors are connected with a DP and a HDMI to the gpu. Btw I can't plug the second monitor, which is 60hz, to the motherboard because it hasn't a dedicated gpu.

When you do major hardware changes, it's recommended to reinstall the OS.
Have you done this yet?

No I haven't, I'll try it.
Thank you for the advice

I reinstalled windows but it didn't work. I tried to reinstall the motherboard drivers and know it works fine.
I hope that was the problem and that it will not occur again.
Thanks anyway

Let's get some more samples then.
What kind of cpu and gpu temps are you getting?

I analyzed the PC and it was ok.

Go into bios and enable A-XMP. Your ram currently isn't running at 3000mhz.
Then try the games again after that.

It's much better, but I still have a little laggy feeling

V-sync disabled?
Browser hardware acceleration disabled?

I don't see an easy fix for this besides disabling the 2nd monitor or getting another 144hz one.
"By having the full 144hz enabled off the same GPU that is also outputting to the 60hz monitor, the frame buffers are out of sync." That's why you're seeing the stutter/lag.

People have found other workarounds besides the above, but results have been hit/miss.
