I tried to launch stalker by going through the library, xray engine crashed on start up. So I installed stalker conventionnaly through steam, I didnt launch it. Yesterday 18 sept I reinstalled stalker because of the recent release of misery 2. I had the same config as I do now, perhaps minus the hard disk which has been integratly copied to my current one. Hello, its not the first time I complete COP, when it got released, I went through the whole game without a problem. Home Discussions Workshop Market Broadcasts.
