I found a graphics tweak on another forum. It seems to be suited for people with a bit older 'mid-end' rigs to get good FPS with the dynamic lighting turned on. I didn't think it would work, but it actually did, and the game looks and runs decent.
Though I believe some of the more lighting heavy areas will still kinda butcher my FPS. I might try the 'Object dynamic lighting' as well.
Go to C:\Documents and Settings\All Users\Documents\STALKER-SHOC (folder seems to differ a bit depending on what language version of the game you're running) and open the file called 'user.alx' with Notepad.
Find these values (starting with ph_frequency and ending with rs_vis_distance) and just replace them with the entries I'm posting here:

Make sure to backup your original file first in case you don't like the changes or whatever. Most of these things are tweakable in the graphics menu of the game, but there seems to be some entry(ies) that are not in there that heavily affects the performance
