Idk if the problem is that Oblivion only use one core... but that think that even one core of mine should be able to handle it. I honestly have no idea what the deal is... Maybe it just won't with my Video Card, if so so freaking piss. I love this game and all I want to do is play it :( and I don't want to have to keep playing on my Xbox 360, Oh god... Anyway some people have told me to turn down the res from 1920x1080 but when ever I do it crash upon start up and black screen, yay fun. Plus no matter what graphic settings I use very low to ultra high, I always get 1-3 FPS. Like seriously WTF? I am run vanilla Oblivion if that matters. Any help would be great, thanks. If you need anymore info please just ask.
