you probably need to reduce your MTU down to something like 1300
vpn reduces the network data  per packet because of the larger header to
transmit the vpn info in the header

ethernet 1500
pppoe 1492
wireless

ping with different size packets until you find the fragment size
which indicates mtu size 

hope it makes sense 
google is your friend for this subject

google :searchterms: mtu fragment ping ethernet vpn  [mix n match to suit]

you may want to rate limit your mouse also [vnc setting]
