nmaston: I am having the exact problem described by pappinr.
Standard fixes aren't helping. Shadowplay is not enabled.
Looking into the WSGF stuff but not finding it to be very user-friendly. Any help would be appreciated.
If you don't have Shadowplay enabled, then make sure to disable any kind of program that adds an overlay. These kind of programs cause problems with the game engine (it happens in Emperor ROTMK as well).
If you have no programs with overlays running, then follow the instructions below to enable the widescreen hack for Pharaoh:
1) Navigate to the following link (GOG.com version only!):
http://www.wsgf.org/dr/cleopatra-queen-nile/en 2) Download the zip/rar included on that page to somewhere on your PC
3) Extract the exe for the resolution you want (preferably to the desktop, the resolution MUST be supported by your graphics card)
4) Rename the exe you extracted to something like PharaohHD.exe
5) Move it to the Pharaoh install folder.
6) Run the game from that exe and select 1024*768 to get the proper resolution.
