I notice that when I play Minecraft, my CPU usage is only around 15 to 20 percent, at most. Is it possible to force my computer to allocate as much RAM, CPU time, etc. to the game, in order to get the best experience possible? Or, is the low CPU usage due to limitations in the JVM or the game code itself?
I have OptiFine installed, and I've already tried using
renice to change the process priority and
-Xmx to allocate more memory to Java. What else can I do?
