urherpesvirus3518: Fallout NV from GOG - might be identical to steam, but I only have the GOG version. I'll be honest and say this is my least favorite Fallout game because it seems so buggy. I have the current GOG version 1.4.0.525 (12010), which I think needs patching to make it playable in Windows 7 (x64). There might be modifications to fix the game I have not tried... However, I stopped playing because there are many places on the maps and points during various quests where the game is certain to crash every time. I spent more time trying to tweak the game to get it running than actually playing it. The Fallout 3 game (and the much different Fallout 4), however, almost never crashes on my PC when I play. I don't have the steam version of either game, fortunately.
streetyson: Firstly, they aren't identical because GOG's version comes LAA (large-address aware, aka 4GB patched) whereas last time I checked Steam's needs patching. But anyways... I have win7 x64 and both games (on a late core2duo PC, with a gt1030 card), and initially I had the same experience as you, BUT it isn't GOG's fault it's NV which was a rushed sequel and well known to be as glitchy and crash-happy as hell. HOWEVER, after following the YouTube video "Fallout New Vegas | FPS & Stability (definitive guide)" by gamerpoets, my NV is as smooth as silk. That guide was developed by and for the TTW supermod, but the fixes work for regular NV installations too. My only criticism of the vid is it tries to cover too many different ways of doing the fixes and pushes MO2 mod manager too much, but the manual methods are in there too and after re-watching and pausing it a few times I got through it all.
