I have had trouble with morrowind and oblivion on my computer (as well as a downloaded version of Witcher) I do have a G-force 6150se. I would like to know before I buy the game... its so agrovating to get a game and not get to play!
thanks for any info on this.

Fallout 3 will not work with win7 64bit for a lot of users.
Bethesda softworks did not bother to fix the issue until now.
Do a google search for "fallout 3 freeze" and you'll see there are a lot of people who cant play this game and there is no fix.
Personally i tried every single solution and nothing worked.
As is the norm for Bethesda, they offer no support for their games and they fix them or not if and when they feel like it.
Apparently in Fallout 3 case they just didnt feel like it.

Hmm well did you try the INI tweaks that were listed online? It was freezing horribly for me but since I applied them it's been completely stable.

Arent yall looking at this from the wrong perspective.
Fallout 3 runs beutifully well on XP and machines of single core processors.

Its not Bethesda's duty to keep updateing a game to the current operateing system and hardware.

Is it possible you have an old machine you could run this game on. I personally bought my current machine for $120 dollars .... even though it runs at the low end graphics .... I have absolutely no issues. All it would take for me to go high end ... is some more ram and a bigger video card.

It is an awesome game and that is why you of more advanced systems are revisiting it. But then you have to ask your self .... is your system really more advanced???

Yes.

A Gforce 6150se is absolutely terrible. No way you could even run F3 on lowest settings.

Lol, the game was released long after xp was obsolete, and long after single core cpus were obsolete.

Yes it is Bethesda's duty to keep updating the game so it works well on the systems it was developed for.
But no, Bethesda does not offer any support for their games, and they dont give a rat's ass if the game works or not on your system.

Dont believe me?
One of the main Fallout 3 developers has made a mod for the game.....so hes making mods instead of fixing the horrible issues this game has....that tells me how much Bethesda and its developers care about customer support.

3 years after release and the game still doesnt work at all on many win7 64bit systems, and yes i have tried each and every solution on the web, just like the other players in the same situation as me.

....

Really? What mod is it?
Indeed, it is Bethesda's.

.....

Aside from an occasional ctd & a certain crash on exiting the game (most likely mod related) FO3 goty runs fine on my win 7 64 system

As long as you do this (even on quad-core processors) it will work fine. Also, make sure the latest patch is installed from the gamesas website. I've done this and it runs fine on my Win7 64bit machine.

Far as i know this is an old fix, the latest patches fixed this issue so no need for this fix anymore, but the new patches created new problems (no surprises there)
There are players that got this issue after installing the latest patches and for these people this fix wont work.
I got the game off Steam a few days ago and its patched to 1.7.03 or something like that.
I tried the ini fix you mentioned, i tried playing in windowed mode, tried disabling antivirus, tried using a different sound device, and a few other fixes i found while browsing for a solution.
Nothing worked, in some areas the game works fine, in others the game freezes all the time.
Funny thing is that New Vegas works just fine.

Anyway i have a dual boot pc and right now im downloading the game on the Win XP. I gave up trying to make this work on win7.
In the 6 months i have been using win7 64bit i only had problems with 3 games, one of which is fallout 3. Im noticing that in the rare occasions i get a problem on win7 64bit, it will stay unresolved, because in all three cases the problem couldnt be fixed despite serious efforts being put into it.

Anyway its a new vegas dev that apparently didnt work on fallout 3 so my point was invalid.

worked for me on Windows 7 64-bit.

Runs fine on my current computer and an old HP with Windows XP 32 bit, and a very weak HP a6763w, AMD Phenom 9150e Quad-Core 1.8 Ghz, Windows 7 Home Premium 64 bit, GeForce 6150SE nForce 430, DX 10, Video memory 128 MB - not nice, but it works!

Present computer: HPE-170t, Intel i7CPU 2.8 Ghz, Windows 7 Home Premium 64 bit, Ge Force GTX260, DX 11.

That’s sad that it would not work for you. Write them a nice real world letter and let them know.

Now I'm kind of concerned. I was getting excited to play Fallout 3 GOTY on my new PC (i7-2600k, EVGA GTX560, Win 7 Ultimate 64), and if it won't run I'll be seriously bummed.

If it does, can I run it on high settings with that hardware? (I've not been a PC gamer before)

I've been playing FO3 on Win 7 Pro 64-bit w/ SP1. I've had a lot of CTDs and blue screen errors (mostly DX memory manager related), but no freezing.

I believe the majority of my problems stem from hardware conflicts/ incompatibilities. I have an ASUS M3A32 MVP Deluxe as my mainboard and I believe that is the root for a lot of my problems. I can't even get Creative's sound drivers to work for my SB X-FI Titanium Fatal1ty Pro (although that may be Creative's fault ); I'm using the default sound drivers provided by MS for my Creative audio card. I'm missing out on all of Creative's features, but at least my sound works properly. Plus the ASUS board I have is terrible for memory problems, especially when all four slots are being used, not to mention the dual RAM (Ganged mode) doesn't even work (all kinds of BSODs and problems).

Same here. I'm using Windows 7 64-bit and have been experiencing freezing issues before this fix but I've read that mostly quad-core users have this problem.

If the game is still being sold in stores then yes, it is there duty to sell a product that works on current tech.

Not really. The official requirements cover what it needs, and that's entirely sufficient.

In which file do you find the second setting? (iNumHWThreads=2)

The FALLOUT ini (not the prefs one IIRC) in the My Games/Fallout 3 folder.
