I feel like I might feel this way if my game wasn't glitched. My dungeons are all EXTREMELY bright, it's very annoying.
In addition, my distant land is glitched, so if I turn it on, what would normally be seen at a distance, as a nondescript layer of ground, appears right next to me. So this means that if the distant land mesh would be above the ground, I cannot see the ground, and instead see nondescript meshes. It's really annoying. Sort of kills my experience.
Hey I also have the Steam version, when I first started using mods with Oblivion I found on the Steam forums that you could change the location of your Steam directory without deleting all of your game content. It basically involves copying all of your games to a seperate folder while you reinstall Steam, as that's not too taxing on the internet usage. In doing this you'll be able to change it to something like C:\Steam so you avoid the complications of the program files directory, this is worth doing anyway as that location can cause problems with a few games. After Steam has installed you can copy the games back to the steam apps folder and hey presto, less problems.
Heres the list of steps to follow, the bottom section is only if you use desktop shortcuts, I only use a couple so it was no biggy, but you can also just delete them and right click each game in steam then select "create desktop shortcut"
This is a lot simpler than it looks and it took me minutes and I'm no pro.
Steps: Moving The Install
1. Shut down steam if it is running (right click system tray icon => exit)
2. COPY the steam directory from the original location to the new one.
3. Rename the original directory. (e.g C:/Program Files/Valve => C:/Program Files/Valve_ORIG or C:/Program Files/Steam => C:/Program Files/Steam_ORIG)
4. In the new directory (not original), delete the file named “ClientRegistry.blob”.
5. Manually run “steam.exe” in the newly copied directory.
6. Watch steam “update” a.k.a verify itself. It won’t download anything/need to reinstall.
7. Run a game to verify it works
8. Delete the ORIGINAL install (e.g. C:/Program Files/Valve => C:/Program Files/Valve_ORIG or C:/Program Files/Steam => C:/Program Files/Steam_ORIG )
9. Done, except for fixing short cuts on your desktop/start menu (see below)
Updating the Shortcuts
1. Find the short cut that needs to be fixed either on your desktop or in the start menu
2. Right click it
3. Chose “Properties”
4. Change the “Start in” property to reflect the new drive & directory path (e.g “C:\Program Files\Steam\” => “X:\Program Files\Steam\” )
5. Change the “Target” value to use the new drive & directory path. The STEAM shortcut can’t have i its target edited, don’t worry it will work! (e.g “C:\Program Files\Steam\Steam.exe” -applaunch 440 => “X:\Program Files\Steam\Steam.exe” -applaunch 440 )
6. Click Apply, Click Ok
7. Repeat
Hope this solves your issue as I don't think there's any other way to get around problems caused by Steam's default directory and doesn't do any other games harm and also stops some windows security malfunctions.
