MAybe that part of the game is poorly coded, but it doesn't mean he is not BN-ed...

I totally understand that Skyrim is in complete disorder right now though, but problems with BF3 too? Or maybe It's the drivers?..

Hate to break the news to you buddy, but I get the EXACT same thing in BFBC2. Granted I'm running it at 32xAA, but I'll be rolling along @ 100% usage and there will be some spot, not a whole lot going on, when my GPU usage drops. This is typically a texture/graphical error in the code. It doesn't mean your hardware is inadequate.
And it's no surprise that the performance improves with clock speed. Although, I'm running my i7 at stock and still maxing these cards. FWIW, with my x3 720 @ 3.6 with the identical video cards, my AMD CPU scored 2500 points better in 3Dmark06.

edit: sorry im usng the latest beta 290 drivers but they messed my system up bad last week, I just couldnt resist trying them again for the ambient occlusion and sli profile for skyrim, it looks much better! the extra shadowning makes a difference alright.
but I was using the latest whql drivers for BF3. BF3 uses alot of cores too,so its 100% defo not the cpu.
Ive got more ram coming specifically for BF3 so I can run it at ultra lol

I don't see where 4GB of system RAM would make it stutter.. Yes the game uses a hell of a lot of RAM but my RAM usage is typically only about at 75%? That shouldn't cause stuttering should it?.. However I should be getting some more RAM in here tomorrow I think. Another 4GB.

But yeah, I just switched back from the 290.36 drivers to the latest WHQL and BF3 runs without any drops in GPU usage.. so it was the drivers that was messing it up for BF3. I'm gonna go back to the 290.36 drivers and see what I can do with Skyrim now.

If they would only release games that worked perfectly. Sighh. I wonder if your x3 720 was bottlenecking them though? Sure it can score higher, but was there a bottleneck is the question o.O

4GHz is fast, its faster than any manufacturer currently markets, and your going to blame it for Skyrim not running smoothly?
Its a well known fact right now that Skyrim runs horribly on the PC as its a console port with bigger textures. It also only uses 2 cores.
The reason why your FPS goes up with a highe clock is because brute force can improve performance from even the shoddiest code, which is exactly what happening here.
I get the same problems as you, but if I turn the shadows down to medium, even with everything set as high as it will go, the FPS improoves dramatically - this is also a well known fix, as the shadows are broken. They dont even look right yet.
The only thing that makes my cards run at 100% is with the ambient occlusion stting turned to quality in nvidia control panel, but I still get slowing down - like EVERYONE else does at the moment,
Some peopel with 5GHz sandybridge cpus are getting much smoother gameplay, and some are still not, Again , its a game issue. And rediculous that they can get away with releasing a broken game.
Its totally unplayable on the PS3 at the moment, just to put the games shoddyness into perspective. Still love it tho!
Click the medium settings preset, so that the optimised draw distances etc are set (because this is what the game was made to run best with on consoles) Then turn the rest of the settings up to high or ultra except for shadows.
Also turn AF to 0, and set it to 16x via nvidia controll panel. The games AF is crap. I also got better smoother gameplay with triple buffering. Hope this helps, infact it will, because this is all fact.
Bethesda is working on fixes, but dont expect anything soon

+rep

I bolded the things that I have done, and I am now getting 100% GPU usage on both cards.

Here are my current settings:

nvidiasettings.png

I now get 40+ FPS at all times using these settings and it appears to be running very smooth as well. I don't have vsync or triple buffering on though. I also changed the shadows to medium wink.gif Everything else is on Ultra. I still have the viewing distances maxed out and on Ultra quality as well. It runs smooth and I get good FPS along with 100% GPU usage so I'm not complaining now. Lol.

~Thanks.

Good good glad it worked for you.

Yes the 4GB of ram really isnt enought anymore as Ive read a few extensive articles and a good conversation between a few guys over on another thread, I also personally tested and discovered the truth to what they where saying. Even though the programme uses a certain amount of ram, it also uses alot as a cache, which it doesnt actually add to the total being used on the green bars, so when it says its only 75% full on the green bars, if you look down at the amount that it says it FREE its actually realy low, on ultra in BF3 I only had 145mb free, this means that although there is plenty of ram left, its all being used as a cache to store textures - the same way as VRAM works.

When the game needs to load textures, they are loaded into the system ram cache, for fast acces by the gpu (if vram is exceeded) and when the total ram cache is filled up and new new textures are needed to be loaded it will have to swap out the older textures, and when it does this, it casues the slowdown. Having more system ram fixes this issue and in a sence basically defeats the need for more vram than 1GB at 1080p and below

The onboard vram is GDDR5, so its very fast, which is why in large muli monitor displays it is more beneficial to using lots of slower GDDR3 system ram, which in turn will give more FPS.

I used to think you couldnt exceed VRAM or it would make a game stutter, this is a general misconception and I only figuerd it out recently.

OMG, after all this time most ppl still don't know what BN is, b/c this is a BN, poorly coded or not... signs are evident...

Like someone said, this game uses only 2 cores, so you really need is faster core, which Intel gives you...

Also there is NO GAME, and I mean NONE that needs more then 4 gigs of RAM... if you know some give us proof

battlefield 3

OH and as a side note if you are hardcore crazy like me and play 4 or 5 instances of EVE at once you're gonna need at least 10 GB cause each instance uses 1.8 to 2.2 GB of ram.

There are loads, basically when you spill over vram you need lots of system ram to store and swap textures in. if you had an SSD then the swapping may not be noticable, but its better if you just have loads of system ram as then textures never need to be swapped out when the space is used up - system ram is also faster than an ssd, but may give a tiny stutter the first time new textures are being loaded if a HDD is loading them. Obviously having an SSD and loads of ram would completely fix the issue

edit: HAVE YOU NOT READ MY POST????

i just said that playing Battlefield 3 uses ALL of your 4GB of ram if your playing it on ULTRA with a 1GB vram gpu - it fills the ram up using it as a texture cache

Great info. Yeah I went and played some more BF3, and I am most definitely getting the stutter every now and then.. and it is a hell of a lot worse on the 290.36 driver version.. it even crashes on those beta drivers. Anyways, suppose I just have to have that extra RAM tongue.gif Sigh, didn't really wanna have to use 4x2GB sticks.. I need to to get some 4xGB sticks thumb.gif
