Vautour

Hi guys, I'd very much like to buy this game, but I cannot read the text on the current resolution. I run a 1920x1080 display and I can't find a way to get the game running full screen. It doesn't have to be full screen, it can be windowed or borderless, but the game window is so small I get a headache trying to read it. I tried the reso program, but it didn't work. Others say their game runs in full screen by default. Any ideas?
