60hz lag 60HZ + 144HZ (lag on 60HZ monitor)

[PixelHamster]

So I've just switched out one of my 1080p 60hz screens with a 1080p 144Hz one (has freesync and I've enabled 144Hz in windows and nvidia configuration).

Now the problem: when using my 60Hz screen every action seems to have input lag, except mouse movement (yes keystrokes lag aswell on this screen)

I only have this problem with hardware accelerated programs like discord, spotify, wallpaper engine (I know that you can disable hardware acceleration but then things start stuttering instead of lagging which is even worse)

Both screens are plugged into my GTX 1070
I have an I5 6600 and 16GB of ram (they don't hit 100% or anything)

I hope someone here knows what's causing this and  can offer a good solution (buying an extra 144Hz screen is an option ofcourse but would be last resort)

seems just like a slow system, I have that on my laptop from work (i5 6200U), haven't found a fix yet

Set both to 60hz. See if the problem resolves itself. I have a feeling I know the reason why if so.

@Mephi00 Why do you think that?

I have similar problems with my laptop from work where its just cause its underpowered, but your issue seems like something else

I did what you said and I don't experience this problem when both are on 60Hz
