Graphics flashing

[cHk4]

Ok running 2x670 4GB at the moment in 2560x1600 resolution, however on some games I've noticed flashing graphics.

Civ 5 the squares/tiles will flash, restarting the game fixes that.
League Of Legends - the interface just flashes non stop

Think Dawn of War 2 suffered the same fate.

GPU temps are abound 50-55 degrees...

Is something wrong with my card(s) or could it be a driver issue? Currently using the latest NVidia beta drivers.

Well first try release drivers and also check what your refresh rate is set to in the Nvidia control panel and make sure that is correct.

With Civ5 its the game I have seen this on radeon 5970s nvidia gtx 590s and gtx 690s in x58 and x79 setups. I think it may have something to do with multi GPU setups. I would be interested to know how it runs on one of your 4GB GTX 670s with sli disabled.

I have also noticed some drivers are better than others but none totally cure it.

To be honest I would do something along the lines of what Kaapstad has said, I would
disable your Sli setup in the Nvidia control panel and then try and play the games and
see if there is any landscape flashing then, if not then I would put it down to the games
not liking multi GPU support.

You could also try rolling back your drivers and see if they make things any more stable
and if so stick with those for a while till a new driver set comes out.
