Is it possible to make the RenderWindow.SetSize command resize without blurring the images?
Similar as using Image.Smooth = false, but for the whole window.
I think there is no way to prevent it, the window has one resolution, and if u stretch it it will blur due to antialiasing (i believe). you can try turn off antialiasing but im not sure if it is already off by default.
To change the windows resolution try to use .Create(..) instead.
sory if that wasnt what u meant, but hope i helped.
