I have two separate partitions on my computer, one for XP and one for Windows 7

When I play this on my XP partition, I get 60 FPS CONSTANT even with enhanced shaders HD, Realistic Lighting, Empirical Weather

When I play this on my Windows 7 partition(With the same mods and hardware and software) I get 20-40 fps that is constantly dropping and going back up making for a stuttery, choppy game

Looking around the net it would seem that the game doesn't work nearly as well with Windows 7 as it does with XP


Can someone please explain to me why Bethesda is still creating games for XP in 2010? Does it have something to do with using a 10 year old engine too?

/Le Sigh

EDIT: Blargh I seem to have posted this in the General discussion forum yet again being the fail I am, can a moderator please move it to the PC forum? Many thanks

Happy days

1) Because it uses an engine built for XP
2) XP still has the larger market share.

One would think they would tweak the engine so that it works just as well on Windows 7.

It is ridiculous that there is such a huge difference in performance between the two operating systems, especially considering windows 7 is soooooooo much better for games (in almost every other scenario)

Even using my 16gb USB 3.0 as Readyboost dedicated memory, Gamebooster along with all sorts of other applications designed to help gaming I still only get 30-40 fps. RIDICULOUS!

My computer is about as close to a super computer as it can get, yet it's bogged down by the fact that Bethesda decided to keep living in the past?

Considering that it's not even Bethesda's engine, there's probably a limit to how much tweaking they can do to it. And that going with an updated version of the engine (if it exists in the way you think it does) is going to cost more just to learn to develop for, place the existing Fallout 3 content into, and may even require additional licensing fees... well, claiming they're only doing it because they "decided to keep living in the past" is just ridiculously narrowsighted.

Now, I'm not personally familiar with Gamebryo development so I don't know which of the above applies, but let's not just assume that it's as easy as you seem to think.

There is no excuse to release a video game in 2010 optimized for a 2001 operating system.

NO EXCUSE.

Except that the 2001 operating system is still the dominant one as well as the previous mentioned possibilities.

"Newer" is no excuse to do what you suggest.

If you have nVidia...

If you have ATI...

That fix does nothing for me. I've already tried it on both operating systems and it does not affect my frame rate even a tiny bit. I suspect it only helps people that have 1 or 2 cores but yeah seeing as I have 4 of the best on the market it does nothing.


And to the other guy I was already having a discussion with - This computer's value sits at somewhere around $5000. I can play almost every single video game known to man at the highest settings with no lag.

New Vegas is no exception if I can play it on my XP partition, but if I play it on windows 7 there is serious lag issues.

There is a serious optimization problem here. Don't try to defend them because as I said, there is no excuse.

By all means - I understand why it would work better on XP due to the reasons you stated, that's fine.

What isn't fine is that Windows 7 does not run the game properly AT ALL. It seriously bottlenecks the performance for no reason, Windows 7 is far superior in every single way to XP.

I'm not asking for Windows 7 to even be equal to XP in playing New Vegas - Just that it doesn't svck.

I have Oblivion and Fallout 3 with Windows 7 and I have no problem. Even without any mods.

I didn't tried FNV yet, but if there is a problem, it's because they did something wrong.

Cause - XP is more stable then Windows 7.

Effect - Game runs better on XP then on Windows 7.

Also, Bethesda does not have to justify it's actions to you or anyone. (Except, maybe Interplay?) If you don't like the fact that they're producing games optimized for WinXP, don't buy it. Just stop whining about "what Bethesda owes you", because they owe you nothing. I do hope they get an upgraded engine for TES5 and FO4 though.. (and stop using Obsidian Entertainment for future games..) But that's entirely up to them.

welcome to the club!

exactly the same here, terrible and not far from incompatible and unplayable with win7 x64 (without the strange dll), but running perfect with constant 60 fps on ultra setting with win xp!
(core i7, GTX480, both windows with latest drivers)




forget it, fallout 3 with the same engine is running perfect on my win7 x64 system!
only new vegas is making so much trouble with win7!

whatever the real reason is, bethesda will never tell here what they have messed up completely with new vegas, i just hope they read this here and fix it as soon as possible!
it is ridiculous enough releasing a game with so much problems with win7 in october 2010, a full year after win7 release!!!

Ah well there you go - I haven't played 3 or Oblivion while I've had this computer so I wouldn't have known that.

Just goes to show - There is something wrong with New Vegas and Windows 7 getting along for some reason.

Doubtful Bethesda will fix it as they never fix anything. let alone problems like this which aren't seen very often.

Guess the most we can hope for is some kind of community fix.

Everything runs better on XP. Don't let the advertisemants fool you again, good sire.

I'm sure this will get patched - there's too much hew and cry about it from buyers. As someone said, its not an issue with FO3 or Oblivion, so something is probably wrong in optimization for the newer operating systems. I'm still on XP and as the OP said about his XP partition, I can max all in game settings and I generally stay at a vertical sync limited 60 FPS. Around large groups of NPCs it drops a little, but no more than those older games. All in all pretty smooth and fast performance - just like FO3.

Wrong.

Every game I can think of off the top of my head runs better on Windows 7.

Do not make ludicrous statements like that unless you have both systems and have ran them side by side - Like I do.

What a horribly inaccurate statement.

Yeah it was inaccurate I just laughed out loud at it and decided not to reply.

I find it hilarious how people think Windows 7 is in some way inferior to XP.

It is literally EIGHT YEARS in front of XP. EIGHT YEARS!!!!

Windows 7 could crush XP into the ground with it's little finger and not even break a sweat.

Workaround: Setup your PC up to dual boot WinXP and Win7. That's what I'd do at least...

I'm unfamiliar with this.

How can I be sure that it will eliminate the problems New vegas seems to have with Windows 7?

i have played the fallout 3 goty with all addons and several mods for 160 hours on the same computer with win7 x64, no performance issues or other problems.
after this i was very surprised new vegas with the same engine is just a pain with win7!

installing win xp again only for this game was also a pain but it seems to be the only solution, all the terrible performance problems are blown away since i play new vegas with win xp.

If that is the case, why is it that Business have not migrated to Windows 7, and have forced Microsoft to extend the end of life of XP?

Most reviews I've read (well - all actually) that compare the two in DX9 gaming show XP being a bit faster overall. May not be the case with your particular system, but you statement sounds about as over-the-top as the person who said XP is faster and more stable. Nothing in hardware and OS software is ever that cut and dried and generalizations are "generally" bad.

I run windows 7 x64 and I have no problems with how the game runs for me. I havn't tried the new DLLs but plan to tonight just to see if the performance does improve at all. I'm running with an ATI 5870, 4g ram, SSD drive, and used the large memory address enabler to make sure FNV runs in more than 2 gigs and the game is totally smooth for me. I occasionally see a graphical flip or evidence that the engine isn't "instantaneous", but nor has it ever been blocky or cludgey - its been smooth even in large cazadore battles with 2 followers vs. 6 or 8 cazadores - good to go.

Assuming there is a problem, it is not universal to all Windows 7 implementations. Also, it is impossible for the poster or anyone else but Bethesda/Obsidian to know how the game was optimized and tested or even if it Was optimized for XP over Windows 7. I think thats silly and makes no business sense, the game has to work right on XP, Vista and 7 because the Box claims so and the companies would catch a ton of hell if they favored one over the other. I'm sure it Feels as though they singled Windows 7 users out because the problems are crippling to those hitting it, but I'm equally confident that Bethesda would Want the game to work well on all of the supported platforms.

We need to wait for a patch, and if there is a massive Win-7 issue, I'm sure they will address it.

Because Windows XP >> Windows 7 >>>>>>>>>>>> Windows Vista?

Why not? Even the majority of the underlay between XP and Vista/Win7 is small despite the revisions of the kernal going to 5.1/6/6.1, the majority of the changes dealt with shedding the last 16bit execution code, and moving towards a unified code base.

The majority of game engines aren't uptodate for X64. The majority of engines will not use DX10 or yet even 11. And the majority of engines still run in DX9.
