I've been playing Vanilla for a long time and have decided to play Minecraft with mods (Valhelsia 3 / 1.16.4) but my GPU (Rx560x [laptop]) is only used to 40% and my CPU is only 70-80% in the game I 1-2 FPS how can that be (I assigned 6 GB Ram to the game)
How much ram does your pc have in total? (The graphics card is almost not used in the game)
8gb ram 6gb awarded
You shouldn't use more than half of the RAM, otherwise the computer will save the data on the hard drive. As soon as this happens, it is over, because then the computer can crash or data can be lost.
