I was about to ask how many resources your using and what’s your total server file size. But if your getting only 60fps with a “blank slate” server your problem is your cpu. That’s a fairly old cpu, when compared to my localhost cpu (phenom ii x4 840) they are comparable in performance. My gaming pc cpu is a 7700k and i have a 1070 from zotac. Also only 8gb of your 16gb sytem ram is available. Try reducing background processes and lowering some graphic settings. Your probably pushing that 6300 too hard.
