I have the msi Optix
So
1. If you have no more than 144 fps in Fortnite you will not get a 144Hz monitor.
2. That can be if Fortnite has a limit.
In for settings limit to 120 fps
No, I have about 144 fps but if I play fortnite my monitor is limited to 120 hz
Then it must be because the Fortnite has a limit. But you will not notice the difference between 120Hz and 144Hz!
And a limit does not have fortnite, a buddy can play on 144hz
Then no idea, if you really have the monitor on 144Hz and Fortnite has no limit, I do not remember. You also have to set the monitor to 144Hz!
But I already notice the difference between 120 and 144
Yes I have
