So VRR means the screen refresh rate will adapt to the fps that your GPU can produce. So if the GPU is pumping out 43 fps, then screen will refresh at 43 Hz. So it's 1 frame per refresh. 43 Hz means the screen is refreshing 43 times per second. If the LG2 can only produce 25 fps for a game, that is outside the VRR range of that screen. So AMD's LFC will kick in and double or triple the refresh rate so that VRR can turn on. So if the GPU is outputting 25 fps, LFC will turn on so the refresh rate is 75 Hz which is within range for the VRR to turn on. This is how the other devices work too. If the VRR range is 48-120Hz for example and the game is running at 25 fps, LFC will turn on and the refresh rate will be 75 Hz and so it will now be between 48-120Hz.

The broader range ensures a smoother, tear-free visual experience even when a game's frame rate dips below the typical 48 frames per second (fps) minimum for VRR. How VRR works within its standard range VRR synchronizes a display's refresh rate to match the frame rate of the content being shown, eliminating screen tearing and stuttering. For most panels, this synchronization only works within a specific range, often from 48Hz up to the maximum refresh rate, such as 120Hz or 144Hz. If your game is running at 90 fps, a 144Hz VRR display will adjust to a 90Hz refresh rate. If your game's frame rate drops to 50 fps, the display's refresh rate also drops to 50Hz. The problem with a limited VRR range For most panels, when the frame rate drops below the minimum threshold (e.g., 48Hz), VRR disengages. The display reverts to a fixed refresh rate, which can cause jarring stuttering and tearing.
