Screen freezes

Hey guys I've joined the server a few days ago and everything was working great. Today when I tried playing my screen started freezing every couple of seconds, like it got stuck for a moment. I have reinstalled the game and changing video settings, restoring to default, restarting my notebook but it keeps happening. I also have the same issue with other gunz servers. Any advice would be appreciated. Thanks in advance!!

Did you update your GPU drivers?

Everything was updated. Ended up unsintalling and reinstalling graphic card and cpu drivers. It works great now.
