In the steam store it is clearly stated that Fallout 3 is not compatible with Windows 7. Can anyone please confirm if GOG's version is W7 compatible?

Thank you very much.

Not only W7, i experienced a lot of crashes on W8 as well. Never tried on W10.

Is this the original release or has the GOG Compatability Team waved its magic wand?

And what about GfWL? Still part of the installation, still a requirement?

I thank yee kindly ...

If anyone can tell me if it does work on Windows 10 ?

It should.

The issue was actually never with the post XP windows OS, but with multi core computers. Fallout 3 had issues with computers thathad more then two cores.
WHat happened was that multi core computers became the standard at the same time Windows 7 came out, and people blamed Windows 7 for the problem.
If you ran the game on a multicore with XP, no problem because XP cannot recognize more then 2 Cores,..one reason why Windows XP became obsolete.

I've never had issues running the Steam FO3 on my machine. Never had a single crash. Maybe I was just lucky?

i5-750
Win7 64-bit pro.
8GB ram.

Probably just lucky.
But ther was a widespread problem with Fallout 3 GOTY crashing on multicore computers .Luckily, there was a simple fix involving editing one line and adding another to the games. ini fiile, telling the game to ignore more then two cores, that fized the problem.

FO3 GOTY played fine on my quad core Win7 machine without issues as well, and without any changes to make it work.

Also to the original poster. This is what it actually says on Steam (copied right from there):

"Notice: Fallout 3 is not optimized for Windows 7 and later"


Not optimized is not the same as Not compatible.

I know exactly the difference. Perhaps the translator did not (see screenshot). Thank you very much for your info.
