I'll show you how to increase your FPS in Minecraft(It's not 100% though) STEP 1: Open your "Task Manager" and proceed to the "Performance" tab. STEP 2: Check the "RAM Usage" STEP 3: Check the "Available Memory" STEP 4: Open your Minecraft Launcher and click "Edit Profile". STEP 5: Go the textbox besides "JVM Arguments" and type the value of your remaining memory. *Note: - Do not use all of your available memory. It is advisable to leave at least 1GB or 1024MB. - 2048 MB or 2GB or memory is enough to run MC smoothly given that you have a good GPU. - Only replace the value of "4", shown at the last image. *Legends: - G = Gigabytes(GB) - M = Megabytes(MB)
