Also remember to go under documents-my games-"Oblivion" and open the configuration file with your notepad application. Under
[Display] you'll find
bAllowScreenShot. Assign that a value of
1. Now when you hit printscreen it will save screen shots to your "Oblivion" game folder.
If it's cloudy or raining and you wish clear weather for screen shots open the console with the tilde key and type
ForceWeather 00038EEE. That will change the weather to clear and sunny for a time.
Tm from the console will toggle off menus if you don't want them to appear in your saved shots.
As someone else said for HDR + AA you set the game to HDR and force AA from the nVidia CP.
If you find grass is killing your card you may locate the
[Grass] entry in the config file and play with values from 90-120 under
iMinGrass. The higher the value the less dense the grass will be. It has a default value of 80 which is very demanding in some areas with its viewing distance turned up and depth of field. Alternatively, you may type
Tg from the console, which will toggle grass on and off.
If you are high level and are tired of fighting CL 40 bears and such nonsense that "level with you", you may bring up the console, target them, and type
kill.
I love the game. I have "Knights of the Nine" as well as "The Shivering Isles". I enjoyed doing all the side quests, guild quests and exploring odd random dungeons as much as I did the main story line.
I highly recommend the below tweak guide for understanding all the options in the configuration file:
