Changelog: at the bottom of the description. Note: Contrary to popular belief, I recommend to use Windows Areo enable.Steam
You can add the mod as a Non Steam Game, if you want to run the game from the steam window. But this is not needed, as long as Steam is running, you can run all versions directly from Fallout_Fullscreen.exe or the shortcut or pin icon.Fallout Mod Manager (Integration, not needed but recommended):
1 Run FOMM 2 Press in Settings button 3 in the last Tab, in Custom Launch Command, put the exe name Fallout_Fullscreen.exe Icon & Access: After put the file in Fallout exe folder. You can Drag to the Taskbar in windows 7 to pin the icon. Or creating a windows shortcut. fose nvse or steam are automatically detected.Mini FAQ:
Why this? Because this make Fallout runs 100% compatible to other programs, you can use ALT+Tab without any delay. Even run programs like Taskmanager on top of the game, or msn chat windows, GECK, gpu-z, etc Is proven that Fallout runs more stable in that way. Why this mod, there are other scripts that do the same? Not like this, auto-detection, full automation, detection of fose or nvse and 4GB mods.Tips about shuttering and smooth game play:
Prerender frames or Flip Queue Size. Has an important impact on the games, specially in the shuttering. And can behave different between cards and drivers. But, If you don\'t got smooth game play is worth trying. The value that work best for me (And I mean A LOT OF DIFERENCE) is in 0 (zero) HD5870 using RadeonPro to put Oblivion and Fallout on zero Queue, this apply the same to NVIFake Fullscreen Mode Windowed - Alt Tab Fix is a utility mod for Fallout 3 and New Vegas that resolves Alt+Tab and crash issues by using a fake fullscreen mode.
