In the launcher there is a a menu where you can choose the resolutions for both uosteam and razor. Unless you want to choose a manual resolution, I would suggest to use the launcher. I have mine set to 1280x800 (on a 1080p monitor) and it's sized appropriately. @Panik8 I'm not sure where you are getting your information. I've been playing with the resolutions and you definitely get a better view with a larger resolution. You should try it out using the launcher. I've done 1920x1080 and it got to the point where it stopped rendering and there was nothing but black borders on the left and right sides of the screen. So it does render quite a good amount of space.
EDIT: You can see the differences in these two screenshots 800x600 1280x800
I was talking about lowering the screen's resolution to have less black border, that doesn't change the game window's size (as far as the game window's pixel count is concerned).
ie.: If you turn your screen resolution down (let's say from 1920x1080 down to 1280x720, while using the same in-game window size of 1100x720, the amount of black border will be smaller using a lower screen resolution, while the "pixels/inch" (ppi) ratio will be lower, making "pixels" bigger.
You seem to be confusing "window size" and "screen resolution".
I just saw this Thread and commenced working on what size i should play etc.....
FYI what i found out by tweaking the forced resolution.
I basically placed items on the floor and stopped adjusting until i saw the items on four sides.
