I have all the top of the line stuff
No offense, but how do you know it is top of the line if you do not know what it is?
Seriously, it does not take a supercomputer to run NL, it really sounds like something can be solved by changing your graphic card settings, or by updating your video card drivers. Again, some system info would be helpful. Also, has been goin on since you bought NL, or is it a recent development. If it is something recent, have you updated or installed anything around the same time that this happened in NL?
