======================
Fixed a crash bug that happened near the edge of maps.
If using detailed terrain, you should now see a small frame rate increase between 3 and 10%
Fixed a bug that caused water reflections to look weird after alt tabbing.
Text should now appear clear on those systems that reported fuzzy text.
Vista users now longer have to run the program as administrator in order to successfully use the autoupdater if they do not have Aces High installed under the Program Files folder. If you still have AH installed under Program Files in Vista, we strongly recommend uninstalling AH and reinstalling the base download into the new default directory.
Fixed a bug that would sometimes cause the Download Skins Automatically checkbox to display incorrectly.
Fixed a bug that would cause the terrain downloader to time out after 2 minutes.
Fixed a potential stutter problem in low detail terrain mode.
Made fixes to reduce the number of stutters that some systems are seeing. We are currently working on an in-depth solution to this problem and expect to that implemented in the next patch.
