How to make IVAN look readable

Hey there my faggets, just started playing this fucking awesome game. So right now I have it set to

WindowWidth = 640;
WindowHeight = 480;
GraphicsScale = 2;
FullScreenMode = 1;
ScalingQuality = 1;

But I notice that it cuts off some text on the upper part of the screen and some menu boxes look like they don't scale very nicely. Is there a trick to this?
I'm on Windoze, displays are 1600x900 and 1920x1080.
