I just forgeted around with some stuff in the hopes of getting oblivion to run on my computer (for some reason the game would either not run at all, or have absolute stuff frame rates, despite being able to run Skyrim at max settings and some graphical mods) and now the game seems to be running smoothly.
I'm pretty excited to get back into oblivion; I've played so much Skyrim recently that I need a change in scenery, but still want to play the same style of game. It's also been long enough since I've played oblivion that I've forgotten a lot of the quests and stuff.
I'll be installing a variety of mods once I make sure that the game is actually running smoothly.
