A question is it possible to play the game with a 3840 x 2160 resolution on my 1080p monitor. I have turned on DSR factor and it worked with Turok 1 but it doesn't work with with this game it doesn't fit the screen correctly. Is there cfg edit or an application that can help me?

but it worked on turok 1 i think the right therm is called supersampling i do it with most games and it works

This doesn't change the fact that in the end it's still just 1080p. Supersampling is just a anti-aliasing technique that sharpens things. When you want native 4K then you need a monitor that supports it.

I fixed it now I used Borderless gaming
