If it runs so well on a Mac with integrated graphics that makes me question why it runs so crappily on my PC. Athlon X2 4400, 2Gb DDR400, 512Mb 7950GTX, 640Gb Western Digital and Vista 32bit. I can get around 50-60fps but it is not consistent at all. It can easily dive as low as 14fps. This was even after a fresh install of OS and game. You would think a game as old as this would run 100fps with my hardware and never see the bottom end of 30. (e.g. this game started off running on a Geforce2 and the graphics upgrade from CoV launch was not THAT intensive.)
