I consider my computer to be relatively strong. It's got a 3 GHz quad core CPU, 8 GB of DDR3 RAM and a Nvidia quadro graphics card. But I am still laggin when playing minecraft, from time to time I'm algging real bad even. As right now, I have started Game booster and give Minecraft a high priority so it will be devoted alot of the computers capacity (see older post for how to do it).
Are any of you having the same problems? What computer specs do you have?
It's driving me insane!
