BFBC2 and stutters

instead of installing Catlyst Control Centre opted for MSI afterburner and it lagged like ****

confused.com

Afterburner is for overclocking the GPU/capping FPS/Recording/Screenshots/OSD monitoring and others. Not sure what you were trying to do, unless you mean using afterburner instead of AMD overdrive to overclock. Am I missing something that I don't know about?
 
Well, no. Format C: is often the quickest way to resolve an issue (or at least rule out a software cause) rather than spend hours trying to work out what is going on, post on a forum for help and then ignore the advice of people that know better than you.

Keep on banging your head against the wall. I'm sure you'll find a solution eventually (which will be a software one almost certainly) and feel smug that you only spent a billion hours diagnosing and fixing it rather than an hour or so reinstalling windows.

Sorry, mate. 3 things :)
First: reinstalling Windows for me is not an hour. I've got multiboot PC with 8 OSes (yes, eight), and I've got 2 bootmenus (from MBR and EBR - old XP style and new Win 7 based, respectively). Coping with this is more than "one hour". And reinstalling all software I've got is next 2 days. And.. and... configuring all this stuff is next 2 days. For your information - there are people who don't have Win and few games on drive only. OK ?
Second: I'm in computer for 25+ yrs and my knowledge is really extensive. I'm troubleshooter as well and I resolve issues for others, OK ? So it's not simple ignoring "because ignoring" other's advice, but BASING on my knowledge & experience I know what's going on with such "advices" with LACK OF BACKGROUND what kind of hard- and software I've got. OK ?
Third: Summing this up. I repeat again. Reinstall is for some lamers who simply don't know what else to do (or what happened). I will NOT reinstall Windows if I don't know what happened with system. OK ?
I just wanted to save you reading such tyrades, but if you didn't want to listen... so read it now :)

So let me "banging my wall" as you said, but I kindly encourage you to READ what I WANT, before I really be mad, OK ? :) All I want - is to confirm, or deny: do people have such stutterings there, or not. With Kepler. That's all. Don't allow me to write with capitals (once again, unfortunately): I DON'T WANT ANY ADVICE. Sorry for making you feel uncomfortable, but read what I want :) It's not an ignorance, but experience. If I wrote I've done everything it means I've done everything, including checking with other Windows instance (clean) and game itself, too. So I wouldn't write NO ADVICE PLEASE if I didn't check it before, OK ? But it was nothing like "format helps, if everything else fails", but I had to reinstall Windows instance due to [old, long story] on my RAID volume, so ocassionally I've checked BFBC2 installing from a scratch, too.

I play BFBC2 on a mobile kepler chip (GT 640LE, OC'd to 890 core 960 mem, at 65C max), works flawlessly. Only thing I noticed is that it works better with dx9 vs dx11 (change it in system.ini). Try that if you haven't yet.

OK, what means "better" ? Faster, or less stuttering ?
If first - it's not important as 660Ti is capable of 60+ FPS with DX11.
If the second - it means, you still have got stutters. But less :) Would you be able to do GPU Mist chart, please ?

I dont have the same card but I had the same issues at the weekend

All I'm trying to ask is are you using Afterburner, if so try something else and see if that helps as your system is more then capable of running bc2

Also install Evilminds BFBC2 configurator and turn off HBAO / Bloom and Vsync off, could also try turning AA / AF off or lower to see if that helps

I run sometimes Afterburner, but it doesn't matter if it's enabled or disabled. Stutters anyway. Please, no advice, charts from other Kepler users might help :) Believe me - I've spent hours (if not days) for changing many multiple sets of options, including SSAA tool which became obsolete with few newest drivers, or underclocking everything possible. Have I to list all of my actions I took to make you stop advicing ? :/ Thanks for help, but it's useless as no help will help, I'm afraid. I strongly suspect driver's lack of optimization for this game for Kepler (6xx and up) and nothing/no one (except nVidia) could change it. Sorry for me, and for nVidia :)

UPDATE

I've checked my son's Radeon 7850 - which is a card a bit weaker than 660Ti - but BFBC2 was playing MUCH MORE COMFORTABLE due to - let's say - no stutterings.* Now, playing this game was pleasure again, like with previous 2xGTX 460 in SLI.

GTX gives 10% microstutter time and 5% f-Rate degradation

but Radeon gives 2% and 0,7% (!!!) accordingly, so 5-8x times better.

Next thing - why GPUMist shows original framerate close to 59Hz ??? I can only presume it has something to do with my monitor overclocking trial in the past. But now I've got monitor which doesn't support 59 Hz refresh rate, so it's odd..

Everything is on the same PC (hardware). Surprisingly, it seems to be ONE game where stutters are higher on nVidia card (vide latest multiGPU comparison with 4 Titans vs 4 Radeons which I saw somewhere here).

Looks like system (Windows) with nVidia card handles interrupts much WORSE for some undefined reason:

Radeon:

And yes - I've disabled EIST, C states and onboard sound. I am using M-Audio Delta 2494 Audiophile as my audio, so no buil-in codecs here... I've checked it with X-Fi as well = the same.

*TBH: stutters appeared, but they were VERY, VERY RARE.

Hello the dpc issue you have is a raid issue. Guess here, you have your 60gb ssd as caching?

I used to do this and had bad audio stutter and high dpc issues I have threads on here about it. Tuck me weeks trying to fig it out and after all different changes. I found the fix by mistake.
I upgraded to a 250gb ssd and had windows alone on that drive, dpc latency was gone also was the stutter.

As a quick test, I put the 60gb ssd into a backup system I had installed windows 7 and setup caching drive and audio stutter and dpc was back. This is something to do with Intel rapid response, the ssd is fine also has I have couple games running alone of it and working fine.

Sorry if you don't use caching etc
 
Nope.
I have no caching. I've got SSD for system and 2xHDDs in RAID-0. DPC "issue" is not an audio issue as I have no cracklings (but I had them in my previous setup and it was main reason for platform change - to current one which was good for long time, until I've changed graphic cards from 2xGTX 460 SLI to single GTX 660Ti = and issue involves ONE AND ONLY game BFBC2).
 
Your Radeon screen is showing high dpc for the Intel storage driver. I would see if you can get the driver updated.
The nvidia is showing high dpc for audio driver.

Dpc latency can be a real pain to fix, most of the time you will think it's the drivers for gpu and it can turn out to be something completely different, like network driver for example.
 
Yes, but it's not the point. Point is what I wrote.
Radeon works completely fine, so IntelISR routine doesn't count. Saying me about drivers update is like slapping my face ;-) Always newest. Except OROM, which in case of P67 is pis*ed off by Intel - they update Z68 and higer only (I mean legal OROMs).
But I serously think about checking external LAN card.. unfortunately only one I have is Realtek-based. Sound card as I said - checked with X-Fi, so not that way.
 
OK, I've found solution... which is unexpected (and probably not seen by anybody else, LOL).

Since today nVidia drivers enable DSR with Fermis and Keplers - so not only 9xx series is able to use it. And then, with DSR and AA turned off = FIRST TIME SINCE A YEAR OR SO stuttering has gone :) Don't know how it works, but it works, problem solved, even game looks a bit better, and works not slower :)
