BF3 in game performance monitor cpu stutter not gpu

post #1 of 21
Thread Starter 
Ok so my game gets great fps like 110 on high using 6870 in cf and 2500k at 5ghz

But it just never feels smooth enough even on all low something just doesn't feel right.

I been through everything i fixed the crossfire stuttering by uninstalling cap and forcing vsync and triple buffering with d3doverider. But it still just isnt right

So looking at this graph my gpu looks pretty smooth but my cpu wobbles like a boss it gets worse if i turn on AA x2 and then even worse at X4 even tho i get 80 fps

What does this mean i dont really understand what this graph shows

Anyone care to fill me in on what im looking at so i can try and find us a fix?

The Graph is in the bottom left in this SS



also i noticed the HUD seems to stutter when i strafe which is when i noticed the slight stuttering

Its also there if i use 1 card so im guessing this is a cpu issue of some sort
What could it be ?

i think its a bug, i read that hyper threading caused the issue but i disabled it and it still felt off and laggy, even though i was getting a solid 60fps w/ vsync on. like you, it still felt like i had frame rate problems even with the graphics turned all the way down.

Ok, so I have had same experiences as you have with BF3.
Pretty sure the post AA setting is the problem. When I completely turn this setting off.
The game flies, the micro stutter becomes WAY less noticeable.

Please test this on your system, and let me know if it solves it.
