The Elder Scrolls IV: Oblivion – Alt-Tab Crash Fix with Windowed Borderless

A quick guide to fixing Alt-Tab crashing/freezing issues by enabling windowed borderless mode.

Additionally how to resolve the stability issues caused by the lack of V-Sync and subsequent high fps that breaks the physics of the game.

Step 1 – OBSE

All credit goes to Floppy52 !

If you already have OBSE installed you may skip this step!

1. Download OBSE (Oblivion Script Extender)
2. Navigate to SteamLibrary\steamapps\common\Oblivion
3. From within the downloaded ZIP, copy the contents of the Data folder into the Data folder in the Oblivion directory
4. Copy the following 3 files from the ZIP into the oblivion directory:
   • obse_1_2_416.dll
   • obse_editor_1_2.dll
   • obse_steam_loader.dll

Step 2 – OneTweak

Installing this mod will make the game run in windowed borderless when selecting windowed mode.

1. Download OneTweak
2. Navigate to SKSE\plugins within the downloaded ZIP
3. Copy the 2 files to Data\OBSE\Plugins within the Oblivion Directory

When running the game in windowed mode V-Sync will no longer work. This will likely result in extremely high fps and will break the physics of the game. Step 3 will address this issue.

Step 3 – Oblivion Stutter Remover

This mod will be used to limit the fps of the game allowing for stability in the absence of V-Sync.

1. Download Oblivion Stutter Remover
2. Navigate to Data\OBSE\Plugin within the downloaded ZIP.
3. Copy the 2 files to Data\OBSE\Plugins within the Oblivion Directory
4. Edit the sr_Oblivion_Stutter_Remover.ini file you just copied. Find the 2 following lines and set their values as shown :
   • fMaximumFPS = 60
   • bHookCriticalSections = 0

Enjoy! Now when running the game it should be stable and allow you to Alt-Tab freely without worry of crashes.
