I'm getting very low fps for some reasons.. (10-15fps)
Edit: might have my pc, I just checked and I had windows defender acting up in the background.
Yes, there may be such a problem for old PCs and laptops due to the large number of plugins. This is especially common on the "Lower levels". Try opening and closing the menu "Esc or X" if you see serious fps drops, for me it instantly raises fps from 30 to 60 at the lower levels, at all the rest everything is more than stable 50-60 fps (I have 10 gen i3 and 1070)
