Actually this is an issue. Lag spikes happen occasionally (especially when opening menu GUI's such as craft and inventory) The framerate looks a lot slower than the Xbox 360 version actually.
No issues as well just the voice chat too . To fix it you have to quit the game go back to the XMB Menu and then Start your server again. That one is working for me !
Also, yeah, voice chat isn't working
