I play minecraft v. 1.14.4 on windows 8.1, 64-bit. During the game, it's very slow, and it often pauses the game, even while I'm actively playing. I run it with nothing else in the background, with everything on the lowest setting and it still pauses almost every five minutes as if I had hit the Esc button, and if I'm playing it on fullscreen, it minimizes the window to the taskbar. I've tried the LWJGL trick, I've tried opening to LAN, I've deleted and redownloaded at least three times, but it's still pausing on me. What can I do to fix this?
