On Dreadnaught’s Deck, when casting Meteor, the performance will drastically drop on impact. On other maps my FPS are fine (around 60, which is limited), on the deck it is around 50. It will drop to 1-3 FPS when the Meteor comes crashing down. Setting the Shadow Quality to Very Low solves those issues (frame rate stays at 60 FPS), but as soon as it is Low or higher than that the problem occurs. Maybe this issue appears on other maps, too, but it is the first map that I experienced it on.
(I have a Manjaro Linux with an AMD Radeon RX 5500 XT graphics card, if that helps)
