Any way to upscale game's windowed mode?

Hi all,

I run a 2k monitor and the text is painfully small in window mode. Fullscreen would be an option except it seems to mess up all my windows when I alt tab.

Is there any way to increase the resolution of window mode game via upscaling?

I tried downloading dgVoodoo2 and using dgVoodooCpl.exe to edit that voodo config file in the game root, but none of the resolution changes seem to persist -- although I was able to verify it does change some stuff.

Thanks,
Violer
