How to set custom resolution (ie. FHD, QHD)

A guide to show you how to set a custom resolution.

Guide

To set a custom resolution that is higher than what you are able to select inside the game, you have to edit three .ini files that are inside the game's folder
(ie. C:\Program Files\SteamLibrary\steamapps\common\Command & Conquer Red Alert II)

The three files you are looking for are:

DDrawCompat.ini
RA2.ini
RA2MD.ini

Step 1

First, you have to put in your resolution in the first file (DDrawCompat.ini). Open it in the text editor put in your resolution at the SupportedResolutions line. So for example, it could then look like this

SupportedResolutions = 640x400, 800x600, 1024x768, 1920x1080, 2560x1440

When you are done, save it.

Step 2

Edit the second file (RA2.ini). The lines you are looking for are

ScreenWidth=800
ScreenHeight=600

Edit these two lines and put in your resolution. So for example, it can look like this:

ScreenWidth=1920
ScreenHeight=1080

When you are done, save it.

Step 3

Repeat step 2 for the last file RA2MD.ini and you are done.

No, there's an option to stretch the cutscenes.

@Amri I assume that's also the case for the cutscenes?

@Deer Lord The main menu by default cannot be changed.

Even launching the game through CNCNet wouldn't change the resolution for the main menu.
So the only thing it will change is just the resolution during in-game.

[Deer Lord]

how about set the resolution for the main menu also??

To fix the game speed go to DDrawCompat.ini and change the fps likiter line to this "FpsLimiter = msgloop(30)"
