So, if you followed our tips how to speed up Skyrim , you should also disable shadows in Skyrim to boost the FPS a little more.
IMPORTANT: We are going to change the shadow resolution instead of disabling them, because some have reported that it can actually decrease FPS if you disable shadows
1. Step To do that, you would open the Windows Explorer (Windows key + E) and go to the following path:
C:\Users\(yourusername)\Documents\My Games\Skyrim
1.1 Copy the file SkyrimPrefs.ini to SkyrimPrefs.ini.bak
2. Step Open the ini file SkyrimPrefs.ini
3. Step Look for [Display] and you will see something like this:
iShadowMapResolutionSecondary=1024
iShadowMapResolutionPrimary=2048
iBlurDeferredShadowMask=3
iShadowMapResolution=2048
change the entries to
iShadowMapResolutionSecondary=512
iShadowMapResolutionPrimary=512
iBlurDeferredShadowMask=6
iShadowMapResolution=512
TIP: You need to play around with the settings. Some settings may work for some and not for others. If you want to completely disable shadows change the resolution to 0 and change the values for fInteriorShadowDistance=0
fShadowDistance=0
