i recently bought skyrim but could not enjoy it because of my poor hardware which is:

i5 520m (2.4GHz)
mobility hd 5650 (2715 hyper memory (?))
4GB ram
win7 64

so what usually helps in other games worked as well in skyrim. in my skyrim\skyrim folder i changed all shadow values to 0 in the SkyrimPrefs.ini
it made a huge difference. now it is almost perfect. i need your help to turn all unnecessary grass and bushes off or just reduce the sight distance.

i would appreciate your work.
