What Breaks When You Turn Off Full Screen Optimizations in Windows 11 Advanced App Properties
- 13 steps
- Needs administrator rights
- Includes a restart or sign-out
Turning off full-screen optimizations in Windows 11 stops Windows from running a game in a hybrid mode. In that mode the game looks like exclusive full screen, but Windows still manages the window underneath. The setting is the Disable fullscreen optimizations checkbox on the Compatibility tab of a program’s Properties window.
Microsoft added the feature so you get the speed of a full-screen game and can still switch to other apps instantly. Disabling it forces that game back to the older exclusive full-screen behavior. This can sometimes raise frame rates or fix mouse stutter in older titles, but it often breaks modern PC features. The setting applies to one program at a time, so only the game you change is affected.
Here is what you can lose in that game:
- The Xbox Game Bar and on-screen overlays such as volume sliders.
- Smooth streaming and capture with tools like Discord and OBS.
- Quick alt-tabbing. It can take much longer, or the screen can go black and the game or desktop can crash.
Turning off full screen optimizations in Windows 11 means unchecking Disable fullscreen optimizations on the Compatibility tab of a program’s Properties window. The game then runs in older exclusive full-screen mode, which can raise frame rates or fix mouse stutter, but the Xbox Game Bar, on-screen overlays, Discord and OBS capture, and quick alt-tabbing often stop working.
How to Access Advanced App Properties and Change Full-Screen Optimizations
You change this setting from the game’s Properties window. Right-click the game icon or shortcut, open Properties, and switch to the Compatibility tab. The steps below walk through the full sequence.
- Find the shortcut or the main program file (the .exe file) for your game on your desktop or in File Explorer. If you only have a launcher shortcut and no Compatibility tab appears later, right-click the shortcut, choose Open file location, and work with the .exe in that folder instead.
- Right-click the program icon. A context menu opens.
- Click Properties at the bottom of the menu. The Properties window opens.
- Click the Compatibility tab at the top of the window. If the tab is missing, you are probably looking at a Store app or a web-style shortcut, which does not have it. Go to the real .exe file instead.
- Look in the Settings section of the tab. It holds a list of checkboxes, including the full-screen optimizations option and others such as Run this program as an administrator.
The option is labeled Disable fullscreen optimizations. Now turn it on and save.
- Check the box next to Disable fullscreen optimizations to turn the feature off. A check mark appears in the box.
- Click Apply, and then click OK to save your changes. The Properties window closes. If Windows asks for administrator permission, approve it. Games installed under Program Files sometimes need it.
That’s it. Full-screen optimizations are now off for that one game, and Windows will use the older exclusive full-screen mode the next time it starts.
By default it also applies only to your own account. To cover everyone who uses the PC, click Change settings for all users at the bottom of the Compatibility tab. Approve the administrator prompt, tick the same checkbox in the window that opens, and click Apply and OK. Even then, the choice is stored for that one .exe only.
What Actually Breaks When You Turn Off Full Screen Optimizations
When you turn this setting off, game overlays, instant messaging pop-ups, and fast alt-tabbing between windows are the main things that break. Your computer falls back to an older exclusive display mode, which stops modern Windows features from interacting properly with the running game.
Windows 11 also has related options in Settings System Display Graphics. There you can set a GPU preference for each app. Recent builds also include an Optimizations for windowed games switch under the default graphics settings. These are separate from the checkbox in Properties, so check both places when a game behaves oddly. Menu names can differ slightly between Windows 11 versions.
1Game Overlays and Instant Messaging Pop-Ups
Game overlays and instant messaging pop-ups stop working because these programs rely on Windows to draw chat menus and notifications directly over your game. When you disable the optimization, software like Steam, Discord, and Xbox can no longer render those notifications on your screen while you play.
If an overlay only fails in one game, check whether you disabled the setting for that game’s .exe at some point. That is the first thing to rule out. Also check whether the same overlay works in your other games, which tells you if the problem is the game or the overlay app.
2Fast Alt-Tabbing and Multitasking
Fast alt-tabbing and multitasking become much slower because your computer switches back to older exclusive full-screen behavior. The game has to give up the display completely each time you leave it. Your monitor can go black for several seconds whenever you switch to a web browser or another app, and the game can even freeze.
This is most noticeable on a setup with more than one monitor, because the second screen also flickers or blanks during the switch.
3Automatic Brightness and Night Light Features
Night Light and other Windows color filters may be ignored inside games when you turn off full-screen optimizations. Games running in exclusive full-screen mode tend to ignore Windows color filters. Your screen might suddenly show full-strength blue light at night, bypassing your custom display settings.
If your eyes notice this, the quick test is to turn the setting back on for that game and see whether Night Light returns.
4Screen Recording and Broadcasting Tools
Screen recording and broadcasting tools can fail or record a black screen because streaming software relies on Windows desktop composition to capture gameplay. Without that feature active for the game, built-in tools like the Xbox Game Bar struggle to capture the game window. You can end up with frozen images or severe video stuttering.
OBS and similar tools have their own capture modes, and some of them cope better than others. Even so, the most reliable fix is usually to restore the Windows default for that game.
How to Fix Issues Caused by Turning Off Full Screen Optimizations
To fix problems caused by turning the setting off, reverse it in the same game properties window. This restores the default behavior.
- Locate the shortcut or program file (.exe) of the game that is acting strangely.
- Right-click the program file and select Properties. The Properties window opens.
- Click the Compatibility tab.
- Uncheck the box next to Disable fullscreen optimizations to turn the feature back on. The box should now be empty.
- Click Apply and then click OK. The window closes.
- Restart your game for the changes to take effect.
You should now have the Windows default back for that game, with overlays, alt-tabbing, and capture tools working as before.
If you also used Change settings for all users earlier, repeat the unchecking there. Otherwise the all-users value can keep the optimization off for other accounts.
If your game still has problems after turning the setting back on, restart your computer. You can also update your graphics card drivers through your manufacturer’s software. If the game was misbehaving before you touched this setting, the cause is probably somewhere else, such as the drivers.
Summary
Turning off full-screen optimizations in Windows 11 usually causes more problems than it solves. It breaks game overlays, alt-tabbing, and recording tools. Some guides suggest changing this setting to fix lag, and it may help one stubborn older game. Treat it as a per-game workaround, not a general tweak. Leaving it on everywhere else keeps your multitasking and everyday experience intact.
