It is nice to be back here, got some time to adventure in the wastes =D
To my extreme sadness, I've been getting a screenfreeze/game stop responding kind of crash that happens randomly, but I can reproduce it quite consistently (in probably less than 10 minutes) on a barebones TTW.
I tested both FO3 and FNV for some 30+ minutes of running around and shooting stuff, but after throwing TTW in the mix the deathfreeze comes, dunno why since TTW doesn't do agressive changes AFAIK.
Tried reinstalling both games and TTW a few times and every tweak you can think at inis/mods/enb/driver/runtime/videocard setup... really done a lot of testing, been trying since June.
Kinda out of options
I'm a medium to advanced user regarding FO3/FNV + mods, should -hopefully- know how to properly clear and restore inis/folders, altough I've also tested in a fresh win10 and win7 partitions, issue was present there too :/
FO3 and FNV from GOG, both come updated to latest patch and in English, as it should be.
(also, tried to get both games from another source just to check if was anything with my copies)
Altough I tried mostly everything, if you guys and gals got any tips, please share!
EDIT: SOLVED
Following the logical conclusion, problem surely was on my end
Uninstalling and reinstalling all C++ Visual Studio runtimes seems to have solved it! Had to grab directly from microsoft and run 1 by 1 (previously had an auto installer that did it all, so much for laziness eh)
And just to clarify, for reference, if somebody has the same issue in the future:
You gotta reinstall TTW (and maybe possibly both games) after changing the C++ libs.
