I'm sorry, but getting 6-9 FPS in some areas is beyond ridiculous on a high end computer. I know about the engine's limitation and how outdated this game is at its core, so I really can't blame it. Instead of ranting like I would have years ago, I decided to move on and uninstall BC.
Still, this leaves me with the relatively uninteresting cities of Cyrodiil. Are there any mods that can help remedy this? With a reasonable FPS loss? All I have so far is ImpeREAL Unique Districts, which looks pretty good, but that only covers the Imperial City. Are there anything else?
