After installation on Win 7 with an ATI 5650 you may install 1GB patches first, so that the game launches ever. Manually save during the game but also does not go in spite of the patches. There remain only the automatic save points. The menu has not been adjusted for the PC, making atrocious.
The performance as a whole is ok, but the game falls after about an hour in a performance-hole and no longer comes out. The ends in infinite Geruckel and just restart the game to help you. I have to say that Sony is forcing me to use their outdated ATI drivers. You may experience problems with more recent drivers not to.
Because of the price I nevertheless give 4 stars.
