hard drop frame

I was playing without any problems or frame drops, but recently there was an incomprehensible frame drop It became 10 frames in the plane before landing on the battlefield, and I would be 30 or 40 frames on the ground, and they would be unstable, and the game would not play and this would harm my ranking and harm me psychologically note that I was playing the game before this problem at 100 or 90 frames, and I have been playing the game for a year, but this problem happened in the last two or three weeks.
