So I bought Oblivion, and of course, my computer was far too shitty to run it. So I went out and got a new video card (It's a BFG 7300 GT). So now, the game displays beautifully. Only problem is, during gameplay, I get about two minutes of smooth gameplay, then the FPS goes down DRASTICALLY for about 20 seconds. Then it's back to nice, perfect, smooth gameplay. Then back to shit. Over and over and over again. I'm all out of ideas. I am by no means computer-smart, but I honestly have no idea what the problem is now. Maybe I need more RAM? I think I have 1G of ram right now. I'm clueless. Any of you computer geniuses know what this might be caused by? I'm running a Dell Dimension 8300, by the way. Everything in it is standard except the video card.
