My minecraft runs pretty well at certain points. But others, not so much. Example: If I am on the surface of a world, and look up, there is 0 lag. But when I look down, I get 1- 3 frames per second. Also, when I am on the bottom of the world, and look up, intense lag. When I look down, zip. I've tried Game Booster, Advanced System Care, and giving MC more RAM. These didn't work too well, although the RAM thing seemed to work a little bit. Anyways, when I quickly switch between Advanced OpenGL on and off, it does not lag for about 5 - 10 seconds. Also, the same when I change render distances, but this helps with some of the lag when it is on short or tiny, but still way too much. I get 10 - 15 frames at good times without lag looking forward (either top or bottom of world). Anyone have any ideas on how to help me?
but idk how to fix it :I
