Dedicated server seems to stutter a bit. How to fix?

I have successfully gotten a dedicated server setup so I can join it on the same computer by using “Open Level: 127.0.0.1” in blueprints, but it seems to stutter a bit. The character movement and physics of certain objects specifically. What could be causing this? Could it be a hardware issue that my computer just isn’t good enough to run it completely smooth? If I haven’t included some info that might be necessary to troubleshoot this problem, let me know and I’ll give said info. Any help is appreciated.
