Jittery Graphics

[nick.lidgett]

Hi guys, i am getting jittery graphics but only when i play battlefield 3, never happened on a "previous" install, which was completely removed when i done a clean install of my OS but now i have installed the game from Origin its not running correctly.

It seems to jitter the most when i pan side to side, but it does do it through out game play in general.

I have tried all the preset graphics option but with no success, the puzzling thing is im getting amazing fps well over 70 on every preset even when it jitters.

here is my spec if it helps

i7-2600k 3.4 @ 4.0
16gb Corsair Vengence @ 1600
CF 6870s @ stock (latest drivers)
50" LG plasma
the game is installed on a OCZ Agility 3 ssd

is it screen tearing? Tried turning vsync on?

(or using a frame limiter..)

hi mate, not sure what screen tearing is but ive tried all presets with vsync on and off, still does it, ill try and limit the frames, what do you recommend

I tried the following and it fixed jittering/stuttering in bf3.

go to ur bf3 installation folder. there should be a file called user.cfg. if not create one using notepad. then post the 2 commands below in the file and save.

renderdevice.forcerenderaheadlimit 1
renderdevice.triplebufferingenable 0

screen tearing happens when your fps is higher than the refresh rate of the display and you pan left or right, part of the image is drawn in one position and the rest in drawn in another.

you can limit your fps with msi afterburner like this:

-settings
1) enable OSD (don't have to set anything to display on screen)
2) Create a keyboard shortcut to OSD
3) Restart afterburner
4) Running OSD will put an app called "riva tuner" in your system tray, its the afterburner icon but has a purple 60 on it
5) Open riva tuner, go in options (click on the wrench) , enable frame rate limiter at [refresh rate]

However, since you did a clean install, it may also be a driver issue. Were you on the latest before? And you've definitely installed CAPs or w/e it's called too? *waits for amd user to chime in*

I posted this link for you earlier today but your thread was deleted.

Anyway, as you're using CrossFire: The dreaded microstutter

Cheers guys, i tried all your suggestion but they dont seem to work for me, i think im going to sack these cards off and just get one decent single card, im certain its CF doing it. I tried playing with just on 6870 but they aint too clever on their own.

Is it like this? I get this stutter On BF3 but only when parachuting? Never been able to fix it. Note when am free falling the game is super smooth, Once I pull the parachute and try turning while looking its a complete mess.

Still waiting on a fix

Hi I had jurky movement with 680sli at a constant 60 fps.

Limiting the fps to 59 seemed to have cured my problems with Vsync off.

user config settings as below

WorldRender.SpotLightShadowmapResolution 256
RenderDevice.TrippleBufferingEnable 1
RenderDevice.ForceRenderAheadLimit 1
Render.DrawFps 1
Render.PerfOverlayEnable 1
Render.PerfOverlayVisible 1
Render.DrawScreenInfo 1
gametime.maxvariablefps 59
WorldRender.FxaaEnable 1
