i knew digital screens use more ressources and a well known tip is to lower refresh rate of digital screens in the settings to get higher avarage fps. But it’s for -average- fps.
This doesn’t really seem to correspond with the bug of a constant 30fps dropping to constant 16-17fps during 20 secondes and suddenly coming back to 30 fps without any particular complexity of the terrain or others reasons. This kind of fps drop looks very strange even if we consider digital screens lower average fps rate.
