Alright so I have an xServe running 10.9.4 all the updates. I know that hardware acceleration isn't supported with a monitor attached. But from what I could find as long as you're using it as a headless system (Remote Desktop) you're fine. Now I've noticed with Remote Desktop or VNC before on other OS X systems that it's horribly sluggish much like I'm experiencing now. But I want to verify if this is just a remote connection issue or could be because of the graphics card even though I'm connected via RD. I tried both VNC and RD and the mouse hardly keeps up and is slow as hell. It's on the local network both machines are hardwired.
