Hi!
When I play games in fullscreen , I have only 1-2 FPS, after the game is running for around 3 sec.
When i alt-tab out, ewerything goes back to normal, and works perfectly. If I click back to the game it works for around 3 seconds, and the FPS drops to 1 again, and stays there.
It hapens only in fullscreen, borderless and windowed works fine.
If i am using 1 display, it works in fullscreen.

I have found this, and tried to solve, but did not worked:

I tried:
-Reinstall all AMD drivers, softwares
-Delede all AMD drivers and software, update windows, reinstall them again
-Set all displays frekvency to 60Hz
-Try to use other presets

Radeon software is 21.4.1, but tried with the newest (21.5.1) too.

Solved, i needed to disable Vsync in game.
My second display worked with Vsyc  enabled, and only that display was on.
My first display (Freesync compatible) is working only when Vsync is off, it did not matter, if Freesync is on or off, i need to disable Vsync, but this is the biggest difference between the 2 displays so i wanted to point out.
