The 'skyrim.ini' contains added lines to enable the used CPU to use more cores for the game.

The used entries are set up for an eight core CPU (brand doesn't matter). You will have to adapt them if you have mmore or less cores available.

'iNumHWThreads' defines the number of available cores.
'iHWThreadX' assigns the cores to a certain thread. 

I strongly recommend to NOT assign a thread to ALL cores. Leave one for Windows (that still runs in the background). Leave the rest of the entries as they are now.
