Serious Sam Classics: Revolution

Serious Sam Classics: Revolution

Weird no fullscreen issue?
I have some new issue with fullscreen that appears only on Revolution not on Classics. And on my new laptop (on the old one it works fine) anyway, when I launch the game it goes into sort of fullscreen but it basically isn't across the whole screen just one part. If I enable the "borders" option at least it centers it in the middle of the screen. The only resolution that seems to fill up the screen is my desktop 1080 resolution. But I don't want to run this old game at 1080p especially on a laptop. I have a ryzen laptop with 2 cards: Vega 3 and Radeon 530 and if I try to run the game on both I get the same issue. So how can I spread the game to fullscreen? Did anyone have a similar issue?
