My minecraft jerky a little or a little more and I don't know what to do I have reduced the chunks, if you drink a potion no particles come and so and I play on 1.15.1 please help me! -Thank you
First, what kind of PC you have, second, I could recommend the Badlion Client, it has a part that improves FPS. You can also switch off various graphical content in your settings (clouds / particles / etc.). Of course, only if you can do without it.
Already added more ram?
No and somehow I don't find any optifine
