Hi! I've just bought the legendary edition of skyrim from steam (to play it legally and for modding) and I've encountered a very poor fps number (around 15-20). I think I've done everything right, I downloaded every basic and plus plugins, and downloaded the biggest and best files where I had to choose. I think my computer is (was?) pretty good when I've bought it a few years back (if that is the problem). I haven't really followed the pcs growing since I've got this pc and a ps3, so I don't know if it I did something wrong or my computer is not as good as I think. If my pc is weak, should I even use graphic mods? My specs: Win 7 64bit 4Gb ram Quad Core: AMD Phenom ll 955 processor 3.20Ghz OCZ Vertex-4 Ata Device VGA: Ati Radeon HD 5850 1Gb vram
