ok weirdly i was checking everything i could obviously to resolve this, we noticed that if we had the screen windowed to 1/2 screen it ran fine but if we went fullscreen, bang dc's abound. So i looked at graphic settings out of interest and changed the framerate settings to 30 instead of 60 and wow its fixed, have been playing today no issue, i reapplyed to 60 and dcs again so that is obviously the issue.
what i dont understand is how if framerate causing me to dc?
