Skyrim Better Performance mod by Mertus.
Description: This performance patch will make your game run like Oblivion.
Can you run Oblivion on max settings but Skyrim only on High or Medium with lag?
This file is for you! You can jump from Medium to Ultra in less than 1 minute!
This patch DOES NOT affect your game in bad way anyhow and do not modify game files, you can remove it at no cost, any time. Please, do not speculate regarding things you don't know.
Also this patch can be used with other d3d9.dll files together, read about this in the documentation (category [PROXY]).
To increase performance at full, try to set custom DeviceID and VendorID values in enbpatch.ini file (HEX values). You can find such info in google, vendor id are two (AMD or NVidia) and device id a lot (videocard model). Try first to set up powerful videocards from same vendor as your card. For example GeForce 9600 GT vendorid=000010de and deviceid=00000622 (but better use other values).
Here you may find VendorID and DeviceID information for videocard:
