I was also using Eset Smart Security (v7). Here's how I fixed it. http://forums.dayzgame.com/index.php?/topic/153010-eset-smart-security-7-or-eset-nod32-antivirus-7-is-causing-low-fpsstutter-this-might-fix-it/

Hi guys, After a clean Win 8.1 install I was experiencing stutter and low fps. Since other games ran just fine, I started looking at Arma 2 and Nvidia settings, but to no avail. After several ingame, config and register tweaks the problem remained, so I started looking at Windows and BIOS, again no solution. Furthermore my CPU & GPU loads were low. I came to the conclusion that it had to be 3rd party software, so I did a backup and a clean Win 8.1 install with just nvidia drivers and arma, the game ran fine. Since my Win8 and Win8.1 software were basicly the same I checked updated software. When I was using Win8 I used Eset Smart Security 6, after the update I used Eset Smart Security 7. One of the changes between v6 and v7 was "Advanced memory scanner". This is also an Eset NOD32 Antivirus 7 update. After the disabling this, the game ran fine, no more stutter, huge fps boost. Here's how to disabled it. Go to "Setup" => "Advanced Setup" => "Computer" => "HIPS" and uncheck "Enable Advanced memory scanner".. This should be about the same for both Smart Security 7 and NOD32 Antivirus 7. My reasoning is that Arma differs from other games since it uses .pbo files, like a .zip file it has to be extracted, this happens on the fly and gets stored in the memory. Since every single thing in memory gets scanned, it causes a huge bottleneck. I doubt I'm the only one affected by this, so this might help some other people as well. If it does or doesn't please post a comment. GreetZ!

I can confirm that 1.198 fixed my problems.

1.198 is now out!

Just got confirmation that a fix will be released within the next few hours.

Daethan, I think you are spot on. After running some other harware tests (same motherboard btw) I can only conclude it's not the harware itself. Started thinking it might be the LGS for my g19 & g13, however reverting to an older version did not solve the issue. The only other change was indeed an BE update.

I'm experiencing the same r similar problem. Been using Arma 2: 103419 since it came out and haven't experienced any problems with it. Now when I join a server, my character loads fine, I can look around but the second I hit a key, BSOD. Checked the dump files. It's always telling me: Critical_process_died with a apparently random .sys file.and ntoskrnl.exe. nvlddmkm.sys / beep.sys / tm.sys / vwififit.sys / cdrom.sys Reverting back to 102591 and all seems well. This seems strange since 103419 has worked for some time now. No problems when running memtest86. Also ran the system file checker and it didn't detect any errors. I'll run some more tests and post the results.
