I don't know if this idea has been mentioned before, I haven't seen it. Anyway, even after patch 1.52 I still have some graphics problems on big maps. After loading up a save game they're especially bad on the first turn, but seem to clear up a bit after that. But there's still choppy looking stuff, like messed up rivers or whatever else. I noticed that if I zoom all the way out, to the globe view, and rotate the globe around once, then zoom back in, all the graphics are cleared up. Not sure if this would work for everybody, but it worked for me, and was real nice toward the end of a game on the huge earth map.
