I have posted a while back also over about the same problem but never actually quite fixed the problem just made it less anoying.
At the moment I`m playing starcraft 2 Heart of the Swarm.
If I play this game as the game suggestes on Extreme/Ultra graphics the game it self plays good.
But when out of battle and in for example the ship with wings of liberty the sound lags and stays behind of the movie.
While I`m playing on the lowest graphics the game support all the lags are gone and the game runs perfect.(But ugly trough the graphics.)
The specs of my computer are:
CPU i7 860 @ 2.8 GHz
GPU: Geforce GTX 560 ti
RAM: 4xDDR3 2 GB = 8 GB
Motherboard: Maximus III Gene
I should be playing the game without any problems on Ultra graphics.
Now I never could understand why this was happening so I started a few stress tests on my system.
The only thing I can see during the stress tests is that one of the cores of the processors seems like falling behind.
As one can see in the attachment.
Is this normal or could this mean there is a problem with my CPU?
If it`s not a problem with the CPU what else could it be any more stress tests I can run to rule this out?
