Hello. I just want to point out right away that I have a good gaming PC very capable of running Minecraft on the highest graphics possible without it running at anything below 40 fps. But it does. It isn't using all of the allocated RAM or resources it has access too, so it is lagging for no reason. How do I prevent lag and have the highest graphics possible at the same time? I simply won't fall for the RAM ­, because everyone knows that that is not what is wrong with the game... It is either nor optimized at all, or there is something wrong with my graphics card or Java. How do I fix this problem?
