|this is not so much a question but maybe some help to peeps.|
Recently installed latest win7 drivers and then in game would get really bad lag spike droppin the fps to as low 10fps at times.
I found what was causing this - (NVIDIA DRIVER HELPER SERVICE) or the process name = nvvsvc.
all i have done is disabled the service NVIDIA DISPLAY DRIVER SERVICE and the lag seems to have gone now and card is running back to full strength.
So i posted this just incase of any help to anyone.
