    Huge drop in fps while playing world of warcraft (on HD 4000)


      I recently bought a new laptop mainly to play World of Warcraft while on the move (have to travel quite a bit for work), and picked the Samsung model which was quite recommended (as per its reviews) for gaming.

      Here's a rundown of specs from dxDiag.

      Please do note that the laptop comes with 2 graphic adapters the Intel on board one, + an nVidia GT650M.

      When I first started playing WoW, the game was running between 80-120 fps at maximum settings, now after doing several system updates, including all drivers/samsung/AV etc...whenever I play WoW it's a hit and miss situation.

      The game either runs smoothly like before, or barely goes above 10 fps on lowest graphics settings.

      It has become very annoying, and I honestly have no clue what might be causing this. Sometimes reboot solves the issue, other times 10 reboots don't do anything.


      Any help is much appreciated.
