Full screen mode does not work

[Марио]

The resolution of my moniker is 2560x1440. The game itself does not let me set the resolution higher than 1920. Regardless of whether I have full screen or windowed, the game takes up only a quarter of the screen. Video memory is 14 gigs. Tried to change the value in the system file, but the values come back at startup. Changing vulkan to dx12 did not change anything. When using alt+enter the game crashes. What to do?

Red Dead Redemption 2 can be a bit finicky with resolutions and fullscreen modes, especially on higher resolutions like 2560x1440. Here's a breakdown of troubleshooting steps, combining general advice with RDR2-specific tips:

1. Verify and Update:

Drivers: Ensure your graphics card drivers (NVIDIA, AMD, or Intel) are the latest versions.
Game Files: Verify the integrity of your game files through your game launcher (Epic Games, Rockstar Games Launcher).
2. In-Game Settings:

Fullscreen Mode: Try different fullscreen modes (exclusive, borderless, windowed) in the game's settings.
VSync: Toggle VSync on and off.
Resolution Scaling: If available, experiment with these settings.
3. RDR2 Specifics:

Compatibility Mode: Right-click the game's shortcut, go to "Properties" > "Compatibility," and try:
Running as administrator
Disabling fullscreen optimizations
Launcher Settings:
Epic Games: In the Epic Games Launcher, try adding "-windowed" or "-fullscreen" to the launch options for the game.
Rockstar Games Launcher: Similar options might be available in the launcher's settings for RDR2.
4. System Settings:

Scaling: Adjust your Windows display scaling settings. Sometimes, a slight change can improve compatibility.
Multiple Displays: If you have multiple monitors, try disconnecting any secondary displays temporarily.
5. Advanced (Proceed with Caution):

Configuration Files: RDR2 has configuration files (often in the game's installation folder or in your Documents). Editing these can be risky, but some users have reported success with:
Changing resolution settings within the files (back up originals first!)
NVIDIA Control Panel (if applicable):
Manage 3D Settings: Adjust settings like "Maximum pre-rendered frames" and "Power management mode."
Display: Ensure your monitor is selected as the primary display.
If All Else Fails:

Community Forums: Search for RDR2-specific forums or subreddits. Other players might have encountered similar issues and found solutions.
Rockstar Support: Contact Rockstar Games support for assistance.
Important Notes:

Backup: Always back up important files (saves, configurations) before making significant changes.
Clean Installation (Extreme Measure): If all else fails, consider a clean reinstallation of the game and your graphics drivers.
I hope this comprehensive guide helps you get Red Dead Redemption 2 running smoothly in fullscreen at your desired resolution!
