My computer can handle it, but I cannot change any of the settings. I think this is because the game crashes when I try to quit so it doesn't change any of the settings I input.

Could someone send me their Oblivion.ini for ultra high settings. The file is located at my documents\my games\oblivion

Thanks in advance.

That wont work, since the game generates that file based on your specific hardware.

To fix that, open up the launcher and set to ultra. Then go into the game settings in game and set them for whatever you want. Open up the console and type in "saveini" without the quotes. They should be saved then.

Cheers, that did the trick.
