Hi, I need some help!

I have applied the HD patches found on this forum and it works well. I could change to the resolution I wanted. But the thing is I want to play this game in windowed mode, because.. well it makes life a lot easier when streaming it on twitch. Is there a way to get the game running in window mode with the rez: 1280x720?

try with DXGL, it gives you a lot of option by rendering a directdraw surface to OpenGL.
If you apply those options to Outcast, simply add the OC3.exe

Thank you, I will try!
