PlasmaPak: I am using Windows 10 + NVIDIA Card (GTX 980) and the only way to really get it to work was using DxWnd. There are 3 Settings you have to activate:
- Main-Tab => Run in Windowed
- DirectX-Tab 1 => switch VIDEO to SYSTEM on fail ... Software rendering.
- DirectX-Tab 2 => Force HEL (last entry).
Game runs fine in window mode. To Bad "Keep Aspect ratio" does not work. This way one could simply use a FULL HD resolution and play the game in full screen anyway without the graphics getting stretched.
Used the latest GOG Version without any mods or patches. NO Compatibility mode.
Tip: Use "Fast 2X Bilinear" or "Full Bilinear filtering" to get a "smoother" image (DirectX-Tab 1)
Edit:
Problem is, that with modern NVIDIA cards (at least, donno about AMD) it's impossible to start settler IV. DxWnd switches to software rendering, which works just fine for me :)
After trying all the Steps in your Post, i spent a bit time in the DXWnd and found a Way to get the Game to run as it should. With Videos working, Fullscreen.
Try the following Steps in the DXWnd:
Main:
- Generic
Run in Wondow
Acquire Admin caps
-Position
Desktop (This is the Part that gets the Game to Fullscreen)
With these options your game should run on Fullscreen just as you remembered when you left it several years ago.
I Have no Idea how DXwnd works and i am generally a newbie when it comes to the Tech-Part but it works for me, maybe it works fpr you Guys aswell. Cheers :)
