Hi

Recently built this Rig

ATI 6990 (had this before I got the MB + CPU)
2700K @ Stock
Asus P8Z68 Deluxe GEN3
16GB DDR3x1600 Mhz
ATI 12.2 Preview Driver
Win 7 64Bit SP1


So I thoght this would pretty much smash BF3 at Ultra but I find that , even though its telling me my FPS around averaging around 80FPS in game , it still feels a but sluggish and occasionally the FPS can drop down to 35-40FPS if there is a lot happening (explosions/ smoke etc)

Texture Quality: Ultra
Shadow Quality: High
Effects Quality: Ultra
Mesh Quality: High
Terrain Quality: Ultra
Terrain Decoration: Ultra
Antialiasing deferred : Off
Antialiasing Post: High
Motion Blur: Off
Anisotrpoic Filter: 8X
Ambient Occlusion: HBAO

I have thought about overlcocking the CPU as I know its well able for it but I honestly thought I wouldnt need to , am I right ? Anyone else with a similar rig getting same results ? I know 2560x1440 is damn high and playing with nearly everything on Very High , I shouldnt moan - but u know , I always want that little more ....especially after forking out so much.

thoughts ?
Cheers
Martin
 
Put Shadows, Mesh quality (draw distance, eats tonnes of fps) and terrain quality all to Medium and turn HBAO off, it will look basically the same and boost your fps by about 35+ so you will keep a solid locked smooth framerate. (HBAO isnt really recommended for MP either, just makes it harder to see people laying down or near objects) If you free up loads of fps then just put terrain quality to ultra or mesh quality back to high, or shadows to high up to you but shadows eats about 7 fps going back to high

Also put antistropic filter to 16x, it makes no difference to performance putting it low.

ALso put anti aliasing post to low or the the screen will be VERY blurry, alternatively if you free up enough performance from doing the above you can turn it off completely and use normal AA deferred and have a sharper more detailed image at the same time as reducing jaggies.


Also overclock your CPU to 4-4.5gz. The 2700k is sold to be overclocked and there is no reason not to it will handle it with ease, BF3 is quite a demanding game and both GPU and CPU intensive so overlcoking your CPU should also help keep your min fps higher.
 
Have i7 at 4 gig and 7970 in X-fire at 2560x1440 get 60fps everything maxed, i dont think it matters what you do with youre rig a, 6990 just aint fast enough. If you take Unigine Heaven at a lower res you are about 1,400 points behind at 1680x1050, so it gives a guide of just what you need to pull maxed in BF3 60fps.

Thanks for this.
 
Yea...definitely overclock the CPU. I recall reading bit-tech mentioned that even on the 7970, they were seeing higher frame rate with the overclocked SandyBridge comparing to a stock clock SandyBridge on BF3.

If you are only using stock CPU cooler, then you would probably best stick with stock voltage. It should take your CPU uo to 4.0-4.2GHz; my 2500K managed to clock to 4.2GHz stable without issue.

Thanks for that guys , will try all suggestions .

I did have a quick attempt at overclocking the CPU using mostly the auto settings but each time the machine would not post and would reset back to stock so obviously I need to do a but more reading on that a find a good guide for my motherboard/cpu combo. Any suggestions on that ?

Thanks again!
 
Can't imagine this is a cpu limit problem, almost certainly the GPU.

To check CPU run perfmon or resource monitor in the background while playing and see if any single core tops out at 100% or near, if so the game gets cpu limited at some times.
 
Not really aimed at this thread, but would someone explain to me why is '60' fps thee golden number to attain? I can understand that the higher the frame rate the better in multi-player (I like far more than 60fps in CS:S - though of course that's easy to hit due to the age of the game), but generally speaking, why is 60fps the desired minimum? Would having 50 or 55 really be a failure or such a big disappointment? :)
 
60fps is a good target to aim for, dips below this are fine particularly if you don't notice them

some people erroneously think that 30fps as a minimum will be smooth based on movies being 24 frames per second - what they don't take account of is that on movie stills the action is blurred where as each frame on a computer is a still image with no blur, so a movie at 24fps each still blends in to the next and looks smooth, where as a series of completely still images with no blend you will see the stutter from one image to the next

basically, set your own minimum based on what you are happy with
 
Would suggest turning off the cpu parking feature in Windows 7. It seems to make Bf3 feel choppy on i7 cpus when enabled.

I don't think that it is realistic to expect constant 60fps on BF3, but minimum frame rate should ideally not drop below 38~40fps, as if the frame rate does dip below that down to say...33-35fps, it is quite noticably not as smooth comparing to 40fps and above on online play.

While most benchmarks seems point BF3 to be a gpu bounded game rather than CPU (while it is true), during some intensive scenes it is not completely unlikely that a stock clock SB isn't fast enough to provide enough scaling for the 6990 and have both GPU working at 99% usage- OP could enable MSI Afterburner onsceen display and keep an eye on the GPU usage to see if they drop during those moments his frame rate dip down to 35fps to confirm if the CPU is limiting the 6990 to deliver 100% performance at those moment or not.

As that is the refresh rate of most monitors. For people with 120hz (3D) monitors then their vsync would be 120fps. Some people will argue that you only need 60fps as that is the max the monitor will show you, others will argue back that they can tell the difference.

I find it different on each game. CSS feels much smoother at 100fps+ whereas some games play perfectly even when in the 40-50fps range.
 
i think BF3 doesn't performance well with CF/TRIFIRE anyway....

i have trifire and even at 1920x1080 on max settings i get 78fps~ but the fps drops too 40's-50's~. if i try anything higher than 1080p the fps goes low to about 40's...

Yes it does i already posted with X-fire 7970 its 60fps and a smooth as pie!!!! Even one 7970 did 45fps, i did a post on loads of games with one 7970 at 2560x1440 they all averaged about 40fps.

What have you trifire i had 5970+5870 before because of vram they would only do about 25fps at 2560x1440.

also if one gets 40-45fps , two should get 70-80fps for about 90-100% scaling, if your only getting 60fps with CF your only seeing 60%-70%~scaling

When I was on 60hz I could tell the difference when it dipped to 50fps way too much.

But now Im on 120hz I can tell when it dips below 110fps way too much.... you can tell the difference between 100 and 120 fps let alone 60 fps. Anyone that says 'you cant see more than 60 fps' is just throwing around words that they have heard, everyone I know who has used a 120hz monitor can tell a HUGE difference in smoothness.

I personally run BF3 settins on medium and a few low to keep a constant 120fps in the most demanding situation and have in not drop below because no matter how fancy the graphics are if it drops below 110 fps it feels horrible now Ive been spoilt.

Battlefield is almost entirely GPU intensive, overclocking CPU wont make much difference at all.
