compared to the previous beta though, its been drastically reduced, you won't really notice it unless you're watching the frame times or are just really sensitive to lag spikes.

One odd thing I noticed was that you get significantly more laggy the more missions you currently have active. I accepted like 14 or so missions and the lag was pretty intense, once I terminated them the lag went away.
