I am using Arma 2 Combined Operations and I have just updated to the 1.56 patch for Operation Arrowhead. I have been running Operation Arrowhead with "Very High" texture detail. Just recently I noticed that after a short amount of time, the texture resolution acts as if it has switched to the "High" setting to lower resolution textures (however, the video settings state that the textures are still set to "Very High"). I find myself constantly re-selecting "Very High" to change it back. Although, it does not appear to be an LOD problem. I can't say for sure if it is associated with the new patch or not, for I just recently noticed the bug. I am running Arma with no additional addons. I am just curious to see if anyone else is experiencing similar problems or if anyone has any ideas for the solution.

Here are some of my system specs if it helps lead to a diagnosis:

-Windows XP Professional 32-bit
-Q8400 Core 2 Quad @3.0gHz
-4gb RAM
-GTX 470 Superclocked (latest drivers installed)
