Yesterday I installed the game in my PC but an annoying thing is happening: during normal gameplay after some minutes, inexplicably the frames suddenly fall making it unplayable, maybe less tnah 1 fps. Before this, the game framerate runs between 30~35 fps.
I installed the latest update (1.3) and also updated the nvidia video driver but no success.
My desktop config:
Windows 7 Professional 64bits
Proc: Core 2 Duo E7300
Mem: 4GB DDR2
Video: Geforce 8600 GT
Sound: Intel 82801GB ICH7 Hight Definition
