If You seem to be doing 0 damage to enemies at long-rage, and wish to make Archery more "Oblivion-Like" please read.
Yesterday, I've been doing some research to figure out why Long-Range archery svcks. Apparently, Skyrim employs a very subtle "auto-aim" feature that for some reason, makes targets at the distance not register damage. (that's just my theory.)

ARCHERY FIX:
Basically, go into your Skyrim game folder, Open Skyrim.ini in a text editor, and add these two lines in the [Combat] section:
f1PArrowTiltUpAngle=0.0
f3PArrowTiltUpAngle=0.0
NOTE: You will now have to compensate for arrow drop more realistically (Oblivion-style).
I tried this last night and it's like I was playing oblivion! I was sneaking and popping enemies near draw distance. I have NO IDEA why Bethesda tried fixing something that wasn't broken, such as archery. But I hope this helps everyone!
(I am not the originator of this fix. I just want to get the info out there to as many people as possible)
Please point others to this post if they are having the same trouble.
Happy hunting everyone, and please vote if this fix worked!
