FPS problem on Olympus map (Apex Legends)

The problem is this. On the Olympus map, specifically in a clearing, where there is a lot of vegetation, the FPS drops sharply, to 40-35. At the same time, in all other places, FPS is kept around 70+. What could be connected with? I haven't played this game before, only started yesterday. Config xeon e3 1230v2, gtx 1060 6 gb, ram 8 gb, ssd Kingston for 240 GB and hdd wd blue for 500 GB (the game is on it), win 10 x64. Judging by my hardware and system requirements, this game should calmly go to ultra 60 + fps
