high fps stuttering when maxing out games

post #1 of 17
Thread Starter 
I've been experiencing this issue with several games, when I max out (or nearly max out) graphical settings I get frame skips even if the frames are high.

I just noticed this with battlefield 2 bad company, if I max out everything the framerates are great, but as soon as I start walking around the map it's like it will eat 1 frame every couple of seconds, it's really noticeable; is this normal behavior?

I thought if anything, it should be translated into lag if my specs cannot keep up with the game, but instead it results in frame skipping, is there a bottleneck somewhere? Could it have something to do with the fact that I have one 4gb ram stick? Also, would a descent hard drive (ex: a wd caviar black) help in any way? For the record, I have my games on the same drive as my OS, just a different partition.

Really interested on hearing your opinions here; much appreciated.

My bet is that either your ram or vram is full, so its gotta keep switching the cache, causing stuttering. Drop the settings, and you should have smooth gameplay again.

My guess is that you're expecting your 6850 to do the same job as a 6990

As much as we'd like to think it's possible... a single 6850 won't/can't handle max settings on a modern game.

of course, I just thought it was odd that it was frame skipping instead of low fps, that's all.

Give me your settings, I'll see if I can replicate the same. We have nearly identical setups (basically).

My 955 @ 3.6, 6850 @ 900, and so on. So tell me your exact settings, resolution and everything for BFBC2 (perhaps a copy of your settings.ini will be useful) and I'll see if I can replicate it.

Overclock your cpu and also your cpu/nb. See if you still have stuttering after that.

Im not confident enough in oc'ing my cpu yet, but I do wonder what effect that would have.

awesome! thanks!

First of all, I have a CRT monitor, so im playing at 1280x1024, I think a 6850 should be OK at maxing out SOME games on that resolution, but again, I could be completely off on this.

I have everything on high except antialiasing at 1x, vsync on.

here's my settings.ini:

[WindowSettings]
Width=1280
Height=1024
Fullscreen=true
RefreshRate=60
VSync=true
[Sound]
Quality=medium
VoipEnable=true
[Graphics]
Effects=high
Soldiers=high
Vehicles=high
Overgrowth=high
Undergrowth=high
StaticObjects=high
Terrain=high
Shadows=high
Bloom=true
HSAO=true
MSAA=0
Water=high
MainQuality=custom
Texture=high
DxVersion=10
Aniso=4
Detail=high
Fov=65


I find it a little puzzling it shows anisotropic filtering as 4x when in game is at x16

Anyway, like I said the frames are actually pretty damn good, it's just that it skips a frame every couple of seconds; same thing happened with crysis 1, the stuttering was a little different but same thing, great frames @ max settings, and it disappeared with lower settings.

Again guys, maybe this is normal for this gpu on those settings, so I dunno...

Ohk I'll see if I can replicate it. Just to note for you, the setting in settings.ini for Aniso=4 works like this: 4=16, 3=8, 2=4, 1=2 and 0=0/1. Similarly this is how the MSAA=0 setting works.

Lastly, before I do this (and I'll do it right after I get your answers) I have two more quick questions:

What driver version are you using (I'm on the Preview 11.10 drivers)?
&
Are you getting this playing MP or SP or both?
