A bit of exaggeration on my part. I'd say about an hour. But after that initial hour or so it loads up without a problem whenever I start the game. Computer is almost 10 years old and vid card has 256 mb. Skuzzy went through some tips for me in another thread. But like I said it runs fine after that first wait.
I have the settings at..
1440x900,
512 texture size (actually thought I had it at 1024,may try that tomorrow)
Detailed water and terrain off.
Everything else is default.
Pentium 4 2 ghz
1.25 gig ram
ATI RATHEON 9500/X 1050 SERIES(HD1900) 256mb
about 5 gig of hard drive left.
