Hi there, I updated my graphics drivers this afternoon and since the update I've encountered a strange problem:

Every 10 seconds(ish) a short 3 second burst of lag occurs when using Windows Aero. For example, if I'm dragging a window (it is easiest to replicate by just dragging a window round in circles), the framerate will appear to drop to maybe less than 10 fps. I normally run games in windows (in order to have custom colour options available) and games also suffer from this if they are run in a window rather than full screen. I've isolated it to being Aero related as if I change the windows theme to basic, classic etc then the problem goes away and, as previously stated, games run normally in full screen mode.

My system specs are as follows:

Intel Core i5 3230M (2.6 GHz)
8 GB DDR 3
NVidia GT 650M
Windows 7 Home Premium 64-bit

If anyone has any suggestions as to what could be wrong/any fixes they would be much appreciated.
