Hi. I recently installed oblivion. It installed correctly, and I installed it straight from the disc. I am playing fullscreen (When I try windowed mode it says there was a massive error) and whenever I look at an npc, object, or pretty much anything other than the ground, I get huge FPS lag spikes, and the textures look messed up and gray.
Can anyone help me with this?
Here are some pictures of what it looks like:
