This is an old topic but still comes up in search engines. I wanted to put in a solution! My game is more stable in windowed mode plus allows me to tab out to wikis, etc., but the only resolution options available were too small or too big. I wanted something around 1600x900. The same solution that worked for Fallout 3 works for FNV, as I found through TweakGuides: http://www.tweakguides.com/Fallout3_8.html Make a backup of your FalloutPrefs.ini, found in My Documents\My Games\FalloutNV or something similar (I'm still using XP, not Vista). 1. Open up FalloutPrefs.ini with Notepad/Wordpad. 2. Search for "iSize" (no quotes) and fill in your preferred resolution: iSize W=1600 iSize H=900 3. Save the file. 4. Right-click the file and, under Properties, tick Read-only so the launcher cannot overwrite the values. Koroush Ghazi's Fallout: New Vegas TweakGuide is at the following link, although the .ini settings modifications are all from his old FO3 guide as indicated above: http://www.geforce.com/#/Optimize/Guides/new-vegas-tweak-guide There are lots of other .ini settings you can tweak to your preference or to improve performance -- I like shorter grass, for instance. Have fun, hope this helps!
