Re: Red Alert 2 Resolution Issue

Sharing how I made it work on my setup (windows 11, rtx4080, 3840x2160 windows res)

1. Modify RA2.ini file (in my installation it is located in C:\Program Files\EA Games\Command and Conquer Red Alert II) and replaced all lines under [Video] with

ScreenHeight=1080
ScreenWidth=1920
AllowHiResModes=yes
VideoBackBuffer=no

In order to do this I first had to modify the file access policy given it was readonly for my user. 

• Right click file, go to properties
• Click the `Security` tab
• Click `Edit` to modify access permissions (a new windows appear with all users and their permits)
• Click `Users (MY_COMPUTER_NAME/Users)` (Note that MY_COMPUTER_NAME will have the actual name of your PC or possibly a random string if you didn't define one when you installed windows)
• Click on the checkbox under `Allow` for the row `Full Control`
• Click `OK` until everyhing is closed, you can now edit the RA2.ini file

2. We need to modify to more settings related to the game compatibility. For this we will go to,

• Right click the RA2.EXE file (the app this time, not the cfg file) and go to properties
• Click on the `Compatibility` tab. Options may be grayed out because of permissions, if not you can skip next step
• Click on `Change settings for all users`, a new window appears

3. Adjust DPI scaling settings

• Click on `Change high DPI settings`
• Click on `High DPI scalling override` (this will enable the dropdown menu)
• Select `Application`
• Click `OK` to close this window

4. Set game compatibility mode to Windows XP

• Under the compatiblity mode section (again, this is happening on the window we opened on step #2) click the dropdown menu and select `Windows XP (Service Pack 2)`
• Click `OK` to close this and other windows

This _exact_ step by step worked for me. I haven't tried to run Yuris yet but I reckon it would be just a matter of re running steps 2 thru 4 on the Yuri's EXE file.

Hope this helps !! Like and subscribe if it did !! (??)

@redshank Nowadays, we usually just install the CnCNet launcher to fix RA2/YR. It's technically meant for online play, but it applies a bunch of automatic fixes that make the game work well without needing any compatibility modes or settings, and those fixes also affect the normal singleplayer game.
