Do I have to do anything with that mod other than run the file? I did that, and I see the blue marble logo at the main menu, but the maps don't look any different. The issue is constant. The water features and the trees look ok, probably because those are animated. Roads, cities, units, and square improvements also look ok. Windowed mode is the same. I tried installing it on this computer for the first time yesterday, and it's always looked like this. Reinstalled a few times.
I've tried adjusting resolution settings in the game and globally with no change. What other gfx card properties should I try to change? Also, leader faces are all white as well. Here's a few more screen caps.
