Various issues

[Slapsticks]

I've been having quite a few issues recently. Number one, I've gotten directsound runtime errors fairly often. However, more annoying than this is that everything looks pretty crappy, I believe since the 1.61 patch (though it might be unrelated). Everything is as if antialiasing was turned down to -8, and is super jagged, to the point where when I turn orders on the map becomes unreadable. The map also looks extremely ugly.
If you need any extra info, I'll send some.
I have the most updated graphics drivers, and am using Windows 7. The game was working perfectly 1 month ago.
