Its almost like im alt+tabbing but im not, its very strange. The game will freeze for a second and sometimes longer but always starts rendering again. This graph is from skyrim, the same thing happens in killing floor.
Im having exactly the same issue.. can anyone help on this one? I´ve already tried to replace the drivers with older ones, but without any success.. it begun very suddenly, I have changed nothing as far as I remember...
I am quite certain that it does not come from overheating as MSI afterburner shows almost constant 75 degrees.... some say that it might be insufficient power supply, but why did this occur a year after I am using the GTX 570M?
I'm not a hundred percent sure this will help anyone but I know it's a very common problem thanks to crappy nvidia drivers.
So what I did was,
When playing bf3 or minecraft or w/e i was playing, every minute or so my framerate would simply drop like a rock and watching my Afterburner on my other monitor I found out it was my usage dropping from 80% to 0 and then back. Nothing is more frustrating than trying to stab somebody in the face with a knife only to find out he moved and is watching you slash at the sky for no reason. So I tried overclocking my card some. The problem got worse. So I did something I considered really stupid. I turned my card down below factory settings. Sounds dumb but it works.
I looked all over the net to find a solution and didn't see one so I thought i put this out there.
