Playing on a laptop which isn’t too good (Minecraft 1.14) and was wondering some ways to get the FPS up.
Optifine is always a good bet, used to get my 8 year old pc from 20fps to 60-70fps, but it hasn’t been updated yet to 1.14 unfortunately.
Another thing would be to reduce render distance, use “fast graphics”, turn off particle effects. Do not allocate too much RAM – 2gb is plenty for vanilla.
But all that is not enough, I can’t play with 10 FPS.
