can you control your game effectively at 12 fps? I can't. Check out this ENB. http://www.gta4-mods.com/misc/enb-fo...end-pcs-f12875
It's made for low end PCs. I use it. Works great. Doesn't look quite as good as the high-end icenhancer or gionights, but it still goes a long ways from the original drab look of the game, and I only lost maybe 5-10 fps average from when I had no ENB. Still very playable.
