By now Ladies & Gentlemen, you're probably frustrated with Windows 10 not running Fallout 3 properly. Crashes, Stutters, etc. After months of searching the web deeply for fixes and tweaks, I have managed to get my game to where I no longer crash whatsoever. I'll explain all the tweaks and optimizations I did. NOTE: YOU NEED FOSE FOR SOME OF THESE. (FallOut Script Extender)
Let me know how these tweaks go for you! I know that these tweaks have been here for years, but they aren't centralized for everyone to find, and people can forget some of them, along some people not even knowing about some of these fixes. If you're feeling generous, I would appreciate your endorsement to get this further out there for others to benefit from. Fallout 3 is such an amazing game, so I made this for lovers of the game like myself to keep the experience smooth & pleasurable.

FO3 Mod Limit Fix - Fixes a MASSIVE crashing bug
https://www.nexusmods.com/fallout3/mods/24056
This plugin fixes the Fallout 3 Mod Limit bug. It allows a maximum of 255 plugins to be loaded. It can also cause an increase in FPS, remove game stutter, and allow for faster loading times especially when using a large number of mods. THIS IS A MUST-HAVE FIX EVEN WITHOUT USING ANY MODS! IT WILL KEEP YOUR GAME FROM HAVING SEVERE ISSUES THAT CAUSE CRASHING. It also means you do not have to merge plugins anymore as long as you keep your plugin count to 255 at most! As a result I have removed the merging plugins section.
