I wanted to say thank you to GOG for fixing, or convincing GSC to fix, the vsync in the STALKER series. Now I don't have to use a 3rd party app to force it. It gives me a little more choice in how I implement AA injectors if I desire, too.

*thumbs up*

I have read about this but what does it exactly do? I have an Nvidia card which uses adaptive vsync so I dont get the benefits of having the vsync fixed and why some users have asked for the original files
