I have two Freesync Monitors, one is 144hz and one is 75hz, both are 1080p. When I enable virtual super resolution on either or both monitors in Radeon Settings, then any game that I run in fullscreen on either monitor gets locked to 75 fps. The games render normally in windowed mode and I get well above 200 fps. But going from windowed to fullscreen and watching the fps counter, I can see that it drops very quickly and somehow gets soft locked to 75 fps. I do not have any kind of VSync enabled anywhere other than freesync. However, this problem still occurs even if freesync is off on either or both monitors. I am not using VSR in the games themselves and am only using it for the desktop. I run my games in fullscreen on my 144 hz monitor in 1080p so the games are not even using VSR, only the desktop. There is no framerate target control enabled, and chill is not enabled either.
If anybody can answer why this is happening I would greatly appreciate it.
