This new method seems to fix it all up and is much simpler, the github page has extra help, and is also a much safer source to be downloading files:
https://github.com/FunkyFr3sh/cnc-ddraw

Simply extract the .zip under releases to the game's directory, open cnc-ddraw config.exe and configure to your liking.

Would suggest using this method, since files are safe and not being passed around and located at unsafe download locations.

Fixes:
- Resolution
- Lag
- Optional Widescreen


Tried dgvoodoo2 & dxwnd on Windows 11 but neither worked or well.

The older method of dropping 3 .dll files in the game folder fixes fps, but no widescreen.
