| | | Decrease anisotropic filtering. Anisotropic filtering, like ENBs, can utilize a lot of graphics memory leaving the video card with little free memory. This can result in poor performance but also stuttering. Turning around in the game quickly or moving from one place to another as the new environment loads can cause temporary freezing or stuttering. |

| == Skyrim stutters and freezes temporarily ==
| |
| The game will occasionally or frequently stutter as you move around in the world. Standing still usually does not cause the game to stutter. The reason as to why this occurs is unknown, however, there are a few solutions for this problem.
| |
|
| |
| '''Solution 1'''
| |
|
| |
| Let your video card's settings handle the anisotropic filtering (AF) and anti-aliasing (AA). For whatever reason, Skyrim's built-in AF and AA cause poorer performance than forcing it enabled in the video card control panel.
| |
|
| |
| # Start the Skyrim Launcher
| |
| # Select Options
| |
| # Turn off ''anisotropic filtering'' and ''anti-aliasing''
| |
|
| |
| '''For nVidia users:'''
| |
| # Open the NVIDIA Control Panel
| |
| # Under 3D Settings click on ''Manage 3D Settings''
| |
| # Click on the ''Program Settings'' tab
| |
| # Under Select a program to customize choose ''Elder Scrolls V: Skyrim (tesv.exe)''
| |
| # Select Antialiasing - Mode and change the setting to ''Override any application setting''
| |
| # Select Anisotropic filtering
| |
| # Change the setting from Use global setting (Application-controlled) to a sample rate
| |
| # Select Antialiasing - Setting and change it to a sample rate
| |
| # Save the settings and exit
| |
|
| |
| '''For AMD users:'''
| |
| # Open the Catalyst Control Center
| |
| # Click on Gaming -> 3D Application Settings
| |
| # Find and select Skyrim as the application
| |
| # Select ''Anti-aliasing mode'' and change it to ''Override Application Settings''
| |
| # Select a sample rate
| |
| # Select ''Texture Filtering'' and change it to ''Override Application Settings''
| |
| # Select a sample rate for ''Texture Filtering''
| |
| # Save the settings and exit
| |

| |
| Disable Skyrim's built-in VSync and enable VSync in the video card's control panel. Skyrim's built-in VSync can cause stuttering and/or poor performance. Disabling it is not listed in the Skyrim options window because Skyrim requires VSync to work properly. If VSync is disabled then the game starts to run either faster or slower than normal and this can cause all kinds of glitches and bugs. The solution is to disable Skyrim's built-in VSync and force it enabled through the video card's control panel.<ref>http://forums.steampowered.com/forums/showpost.php?p=28503710&postcount=2</ref>

| === Disabling Skyrim's VSync ===
| |
|
| |
| # Open the Skyrim folder in your document, usually C:\Users\[YOUR NAME]\Documents\My Games\Skyrim
| |
| # Open the file SkyrimPrefs.ini
| |
| # Press CTRL+F and find ''iPresentInterval''
| |
| # Change the value from ''iPresentInterval=1'' to ''iPresentInterval=0''
| |
| # Save and exit
| |
|
| |
| For both nVidia and AMD users the procedure is similar.
| |
|
| |
| # Open the video card control panel
| |
| # Select 3D Application Settings
| |
| # Select Skyrim as the application
| |
| # Enable Triple Buffering
| |
| # Enable VSync
| |
| # Save and exit

| == Can't interact/use action (E keyboard) with ore mines, smelter, work bench, and other crafting stations ==
| |
| A bug may occur during gameplay where the E key, or the action/interact button, does not work and there is no message displayed to indicate why you cannot interact with an item, like 'Enemies nearby'. The reason this occurs is unknown and may not have anything to do with the save file so loading an old save file in which the interact button worked does not guarantee that it will work again.

| '''Solution'''
| |
|
| |
| Bind a dragon shout like Fus-ro-dah and shout. This should fix it.

| == Zoner's High-performance ENB causing purple lens flare ==
| |
| Zoners High Performance ENB, also known as zENB, can cause purple lens flare to appear when the sun is rising. This problem seems to happen frequently in Whiterun.
