I quit the game and went to the launcher. I tried playing the game at the 640x860 resolution and with the lowest detail settings. Still my framerate stayed at 1-10 fps.
I also tried pressing Alt+Tab during the game as said in the manual, but it didn't help at all.
My computer meets the recommed system requirements, in fact, it's more powerful than recommed.
2.93 Ghz Intel P4 CPU
1024mb ram
ATI X700 pro 256mb videocard (also overclocked for gaming)
with latest Catalyst drivers (v.6.5)
SB Audigy 4 soundcard
I closed all background programs including firewalls with ctrl+alt+del, but it didn't help.
Please help...i hate playing with this low framerates

Edit: The movies and the main menu lag really much too.
