Elder Scrolls V: Skyrim System Requirements And Performance Tweak

First of let' take a look at the System Requiments for Elder Scrolls V: Skyrim, then we take a look at the ultimate performance tweak for maximum pc gaming.

Minimum Specs:
Windows 7/Vista/XP PC (32 or 64 bit) 

Processor: Dual Core 2.0GHz or equivalent processor 
2GB System RAM 
6GB free HDD Space 
Direct X 9.0c compliant video card with 512 MB of RAM 
DirectX compatible sound card 
Internet access for Steam activation 

Recommended Specs:
Windows 7/Vista/XP PC (32 or 64 bit) 

Processor: Quad-core Intel or AMD CPU 

4GB System RAM 
6GB free HDD space 
DirectX 9.0c compatible NVIDIA or AMD ATI video card with 1GB of RAM (Nvidia GeForce GTX 260 or higher; ATI Radeon 4890 or higher). 
DirectX compatible sound card 
Internet access for Steam activation

Next, this is what exactly you need to do to have the max of enjoyment when playing this game:



For getting that maximum graphic fidelity to performance ratio.
Feel free to rep if this works for you.

You should be able to get 40+ with this setting with the game looking better than high settings.

Here's what Ive found so far. 
Shadows are very taxing on the system, the difference between high/ultra shadows is negligible and not worth the performance dip.

FXAA >>>>> regular AA in terms of looks AND performance.

This machine should be able to run in between high and ultra settings @ 720p.

Here are my settings:
In ati catalyst controls, make sure everything is set to use application settings, or you might encounter graphic problems.

Select High preset.
turn off AA.
Make sure Anisotropic Filtering in at 8x.
Go to advance.
Under Details set Radial blur to high, Decal to ultra, and shadows to Medium
Check FXAA
Check reflect sky for water details
Go to view distance tab.
Set every distance to max. Set distance object detail to High.

Additional Important Tweaks:

Make sure you force V-sync OFF in catalyst control. V-sync causes mouse lag and lower performance in this game. 
This can be done: Wait for vertical Sync - performance (always off)

Make sure you uncheck ATI surface optimization: this causes problems with certain textures. Unsure if it lowers performance but better safe than sorry.

Optional Tweaks: (will see slight performance drop for increased graphic fidelity)
Go to Documents -> My games ->Skyrim
Open SkyrimPrefs

Find:
uiMaxSkinnedTreesToRender =20
this basically controls the amount of trees rendered on screen at one time, you can safely set this to 80 without much performance loss

also
find:
bTreesReceiveShadows=0
bDrawLandShadows=0
This turns on self shadowing for trees and land.


That is all the information you need to know about System Requirements of Elder Scrolls V: Skyrim and its arguably ultimate performance tweak for maximum pc gaming.
