Computer Lag Spike Issues

[evilchaseofdoom]

I have a decent computer, but have been experiencing constant lag spikes. It isn't a connection issue but more from my computer's end. I only play Zodiac so I can't speak for how it functions on other servers but my screen constantly freezes for a split second hurting my cast time and screwing up my combos. I updated my graphics drivers, play in full screen, disabled OpenGL, weather, particles, etc and still have this issue. I have windows 7 and am on a laptop if that helps. Any suggestions would greatly be appreciated, thanks!
