Fallout 3 Strange Lag

[Zerk]

Hay Guy's.

I had no idea where to post this, But it seams to be a Win 7 problem cause I don't remember it when I had XP Pro 32.


It Runs Good at 60-80fps , but now and then it jerks, seams like Lag but the fps stay up like 40fps , ..

I seams like when I turn it jerks 2-4 times and then it's ok until I turn the same way again.,.


All I remember was it never did this in XP. and Now I have a GTX 285 instead of 9800GTX KO.


Is win 7 Working ok with Fo3?

Specs.

Win 7 64bit pro.

GTX 285.

E8400

4GB 1066mhz DDR3




Thanks any help!

Which driver version are you using for your GTX 285? Have you applied all available patches to Fallout 3 yet?

Try turning off anti-virus security. It's been known to cause issues during gaming.

It's not lag; it's called microstuttering, and there is no sure fire way to fix it.

Look here, down about 3/4 of the page, and it will explain microstuttering and possible fixes (I tried all of them and they never worked).

I thought microstuttering was caused by duel GPU's such as GTX 295 or 4870x2.

I got the 2 first patches, After that it says it's just to support the "pit mod".

Using 191.07

I have a similar lag on Fallout 3 after updating nvidia drivers from 182.06 to 191.07 (for Red faction guerrilla).
Strangly it happens mostly indoors when fps should be higher.

System specs:
CPU: E6850
GPU: 8800GTS512
RAM: 3GB
OS: Vista ultimate 32bit
Resolution: 1440x900

no OC

Question, does the performance get progressively worse or does it stutter down to 40fps and bump back to 80fps right away?

 

[Zerk]

Yea pretty much.

My Buddy has it on PS3 and XBOX 360, he says it does the same thing on them, Must be the game.

 

[hypocrisyforever]

Yeah, i mean, i had driver issues back in the day with SLI, and it actually took a few patches for them to fix it, but that lag spike isn't something I've come up against. I had a more progressive problem where the fps would drop over time.

No, microstuttering is the delay from which the game tries to sync the physics with the graphics; the graphics has to skip ahead while the physics stays the same. It'll be present at all times, unless you're a lucky one that can get it to go away!!

Check out that link and it'll have some more info about it and how to fix it if it progresses.
