A friend of mine recently bought a GTX 570 for his rig mainly to play BF3 on Ultra, which it does but there is one small problem..
You see, the game runs incredibly choppy and stuttery. Every 1-3 seconds he gets major stuttering and the game is pretty much unplayable. He didn't have this problem before, on his GTS 450. So.. Is the CPU bottlenecking the GPU perhaps? It's a i7-870 @3.1 GHz. He also has 4 gigs of XMS3 memory. His harddrive is insanely slow .. WD Caviar Green 1,5TB. Seems to be part of the issue.

Hope to get some feedback! Thanks :bounce:

Didn't know the 870 had hyperthreading, haha :lol:

Did a fresh install of the Nvidia driver but nothing changed. (285.62WHQL)

He's got a Corsair TX750, and oh dear lord his case is so untidy..

Doesn't the harddrive just determine how long the loading times are and such?
 
i'd say he ndeeds more ram, and possibly needs to use driversweeper to clean the old drivers properly in safe mode. Re-install the game also might help. Is he running it on the same detail settings/resolution as previously? or higher settings? Reduce texture detail and AA, having it on ultra will fill up the vram causing stuttering/bad performance.

I notice my game bottle necking very VERY bad. I don't know what the issue is either but it is very annoying and almost unplayable. What happens with mine is that it is smooth game play and then shortly following is an fps chop or what i think it is.

Running it at 1080p, no AA, 8AF set the quality to auto. (ultra, high, high, etc)
We'll try driversweeper and see if it fixes it :)

If he's running on High settings and still getting huge stuttering then VRAM is likely not the issue. There's really only 2 possibilities left:

1.) The PSU cannot handle it. What PSU does he have?
2.) Not enough RAM or runs out of RAM during BF3. This will cause severe memory thrashing as BF3 switches from using RAM to your 5400rpm hard drive...ouch.

1. Corsair TX750
2. Corsair XMS3 1600MHz 4GB i believe. May be 1333, not sure. It says only 2GB are available though.
Sounds like harddrive is the isse then. I'll be sure tell him so ;)

Hard drive shouldn't be an issue... maybe he should just reformat and do a clean driver install. how much of a pain would that be? It's still a 32bit application so 4gb should be more than enough.

I have noticed my hard drive is not reading things very slow, and I am having the same issue as the OP as well. Could my hard drive also be an issue with the shutter I get while playing multiplayer?

heres the solution.Its all over google
Open the console by pressing ~ key on keyboard
type in these commands.

renderdevice.forcerenderaheadlimit 1
renderdevice.triplebuffering 0

After entering these commands the problem will be solved.You will be amazed as to how responsive the game is even at 30 fps.This is a NVIDIA driver probelm which will be fixed in a future driver release

Could be, how much RAM do you have, 32 or 64-bit OS?

If he has 2gb of RAM available then of course it's the problem on BF3. What else could it be?

I'd try what he said. I'm experiencing the same thing we'll see if this fixes it.

Thanks. Hope this works.
