Guild Wars 2

Hey Support.

I have been having a bad problem with the game recently and i cant seem to find out what is causing it. My games visual freezes but the sound keeps playing. This usually happens right after my attacks losses sound. I first thought it was my Nvidia drivers so i updated them to the latest version but it keeps doing it.

Here are my pc specs please any help will be appreciated.
