Excellent! Another one to the rescue! That's +1 rep to you too! For helping out isa0005.
@TheCataphract: in terms of improving game performance, eliminating shadows and stuff like that certainly helps, but I've also noticed that my game performance is boosted immensely by changing the "filter" option under advanced options from whatever it was before down to "trilinear" or even "bilinear", the latter one being used if you put all your settings on the automatic low settings. I can still play with "high" unit detail and "high" texture quality too! I could probably even get away with "highest" level unit detail if I wanted to, although I find that during enormous battles with three or four armies my game gets a wee bit too choppy enough for my tastes, so plain-old "high" is optimal.
