*After upgrading to update 1.12.1 my minecraft is not playable, with extreme FPS drops.*I can't determine if the problem is because of upgrading from minecraft or windows 10, because i haven't been playing minecraft windows 10 for a while.FPS Falls occur in all my worlds, new or old. Before the problem, I played at maximum FPS, with no apparent drops, but when I entered recently, I couldn't even move.

  The configurations of my notebook are: Intel Core I7 processor with 8 GB of RAM, Nvidea gtx 940 mx graphics card with 2GB of dedicated RAM.

I will attach a world and try to put a video
