This mod is intended for everyone, and can be a good boost and stabilization tool for the game.

And a great tool for mod developers.


1: Put the Oblivion_Fullscreen.exe file in the same directory as Oblivion exe.
2: Run the game using Oblivion_Fullscreen.exe

Uninstall: simple set back fullscreen in Launcher Options, and run the game as usual.
Changelog: at the bottom of the description.

Contrary to popular belief, I recommend to use Windows Areo enable.


You can add the mod as a Non Steam Game, if you want to run the game from the steam window.
But this is not needed, as long as Steam is running, you can run all versions directly from Oblivion_Fullscreen.exe or the shortcut or pin icon.

Oblivion Mod Manager (if you run the game from there):

1 Run OblivionModManager
2 Press in Settings button
3 In Oblivion Command Line, put the exe name Oblivion_Fullscreen.exe

Icon & Access:
After put the file in Oblivion.exe folder.
You can Drag to the Taskbar in windows 7 to pin the icon.
Or creating a windows shortcut.
obse or steam are automatically detected.

Mini FAQ:

Why this?
Because this make Oblivion runs 100% compatible to other programs, you can use ALT+Tab without any delay.
Even run programs like Taskmanager on top of the game, or msn chat windows, Tes Construction Set, GPU-Z, etc
Is proven that Oblivion runs more stable in that way.

Why this mod, there are other programs that do the same?
Not like this, Oblivion Fullscren try to achieve complete automation, in a non intrusive way,
and correct a lot of issues that static methods can't.

Tips about shuttering and smooth game play:

Fraps can introduce shuttering in game, even when is not showing the numbers.
I recommend to close FRAPS from the tray area before playing
and use the Oblivion console command TDT to see the FPS

Prerender frames or Flip Queue Size.
Has an important impact on the games, specially in the shuttering.
And can behave different between cards and drivers.
But, If you don't got smooth game play is worth trying.
The value that work best for me (And I mean A LOT OF DIFERENCE) is in 0 (zero)
HD5870 using RadeonPro to put Oblivion and Fallout on zero Queue,
this apply the same to NVIDA and is called Prerender or frames ahead.
This pictures are for referece:
Nvidia: Using drivers
ATI: Using RadeonPro

For some people, Disable Desktop Composition, can reduce shuttering too
But can Introduce Tearing.

Any Issues?

Please comment, any feedback is welcome.

I can't Alt + Tab
You need to left open another window, for example a folder, if you forgot, use control+alt+del to open task-manager, and try again.

The mouse pointer does not appears when alt+tab to other application
Go to the bottom of the screen and click, like trying to click the task bar, the mouse appears again.

I cant WinKey+Tab to use Aero effect (only Vista and 7)
This effect cant be started in Oblivion, first alt+tab to other window.

Brightness, Contrast and Gamma Correction
In game Gamma does not work in this mode, there is a perfect tool for that.
Fix using Gamma Panel: download link -> http://majorgeeks.com/Gamma_Panel_d2796.html

If you have a non standard version of Oblivion on steam that does not work
may be an special version, report the AppID, you can get that number simply creating a Desktop icon of the steam game
.Secondary button, create a desktop icon, in steam
.And then in the desktop secondary button and properties, and copy the number, to report it here.

Blurred textures, you see like blur 5 meters in front of your character
That's because Anisotropic filter fails to work in this mode (For some videocards/drivers)
To Fix this issue, force anisotropic at Driver level in your driver control panel, or by adding the exe's that run to your profile program.
(Remember Anisotropic is NOT Anti-aliasing)
HDR + Anti-aliasing + Anisotropic works just fine, ask in the comments if you need help.

If you using Stardock themes
It seems to be necessary to adding Oblivion.exe to the Exclusions list in Stardock MyColors (reported by xombie37)

Two monitor or some setup that dint work
Try using Properties in my file and choose compatibility "Disable Desktop Composition".
But report this, because is not intended in that way.

I want to deactivate OBSE
Add a minus sing in the file name, example: rename OBSE_loader.exe to OBSE_loader-.exe, and that's it, is no longer loaded. (this apply to the non steam version of the game), to disable obse on steam proceed as usual.

If manual configuration is required
This ONLY apply if you don't have write access to Oblivion.ini
(if is not intentional ask how to fix this)
First try to set Windowed mode in the game options and the same resolution as your Desktop

This can be done also in Launcher Options or OblivionModManager

or in (My Documents Oblivion ) Oblivion.ini

For example change this parameters:
iSize W=1680
iSize H=1050

And set windowed changing this to 0
bFull Screen=0

Please report any troubleshooting you need to perform, or the rate of success of this mod, good feedback is very useful to all.

Let me know if it works out of the box too.
