I have 128MB RAM. Shouldn't that be enough for a game like Europa Universalis when it works fine for all other games, including several games I'd expect to require a lot more system resources?
My sound drivers are the most recent, but they're still not very recent, so as to speak, so maybe that's it... Didn't know I could insert an audio CD, BTW, so thanks for the tip. Now I'll just have to see if I have anything suitable.
