I increased the antialiasing in NVIDIA's control panel to see if the game could handle more than 2x now that I haven't been getting as many oom's. So I went a bit overboard and increased it to 8x. When I'd hover over a building in the city construction menu, the icon would be blank for a few seconds, then it would appear as it should. The reason I mention this is that there is a lot of weird graphic stuff in the debug file that you may be wondering about. The game crashed with an oom when the research screen came up, which happens a lot (but the debug file always says it's after a NPC battle).

File includes debug and autosave.
