Make sure you put the thread priority of the server on above normal. Don't do high, above normal is enough.
Also run windows media player or srcdsfpsboost.exe. Is that srcdsfpsboost.exe running already, I cant see the name on the cmd window (make a bigger pic next time). windows has a low fps limit when you are just on the desktop but either program force windows to unlock this limit.
I guess just do normal tweaking to use less system resorces if your still having issues.
