After running "msconfig" or "Autoruns" I have noticed that amd_dc-opt (AMD Dual-Core Optimizer) is listed among the startup aps, is this normal?
Why is "AMD Dual-Core Optimizer" on my system when my CPU is a Phenom II X4 Quad Core?
Thanks in advance.

Did you upgrade from XP to Vista?
Go to add/remove programs and see if it's listed there, if so, uninstall it.

It is nowhere to be found in "Programs and Features".

I know, but you could have been running 64-bit XP.

Thanks, I finally found it in ADD/Remove. It was listed as Dual Core Optimizer, I was looking for "AMD".

Few games like the new batman game auto installs DCO even if you use a quad core. I just remove it (DCO) after the games installed.
Just thought I would add that encase that's where its coming from.

Thanks a lot for the heads up. It makes a lot of sense because I have installed a lot of games that I ordered from Goozex recently. I think DCO was causing me to crash because "Programs and Features" tells me it was installed on 8/29 and that is right about the time I started having issues.
Batman: Arkham Asylum is freaking awesome game, I was up until 6AM playing it and I had no idea the time flew. Well worth the money indeed.

I must admit the only thing I am not loving is the developers at Rocksteady bending to nVidia's proprietary PhysX garbage instead of going the neutral (Havok) or Open source (OpenCL) route.

That's where we differ, Physx just rocks for detail and FPS performance.
I max this game out as high as she will go with mad eye candy in drivers and still pull more FPS then my eye can ever see @1920x1080 1080p.
Cant wait to see what the 295 GTX top clocked monster card will do tomorrow.
Clocks on it are same as mid range 285 GTX X2 .
Giving the fact that its easier and cheaper for game makers to program to nvidia then ATI architecture, I doubt it will change any time soon.

I found that Batman installed this on my computer as well. Suddenly my otherwise smooth running system was hanging for a few seconds doing the most menial of tasks (simply opening the control panel!) I looked around and lo and behold there it was installed on the same day/time as Batman! Removed and now my machine is happier! Thanks to the original poster for bringing up this topic! It helped!

Interesting, I've never noticed this at all.
....I haven't been experiencing any issues really, but I'll uninstall this little bugger anyway!!
This is what it is though:
AMD Dual-Core Optimizer Version 1.1.4
Description:
The AMD Dual-Core Optimizer can help improve some PC gaming video performance by compensating for those applications that bypass the Windows API for timing by directly using the RDTSC (Read Time Stamp Counter) instruction. Applications that rely on RDTSC do not benefit from the logic in the operating system to properly account for the affect of power management mechanisms on the rate at which a processor core's Time Stamp Counter (TSC) is incremented. The AMD Dual-Core Optimizer helps to correct the resulting video performance effects or other incorrect timing effects that these applications may experience on dual-core processor systems, by periodically adjusting the core time-stamp-counters, so that they are synchronized.

I remember the discussion about this when the first line of Phenoms arrived. I'm sure those threads can be find somewhere way back in the forum. DCO causing problems and shouldn't be used with the newer CPU's, it was ment for Athlon X2's and this had been fixed in the newer line of cpu's somehow.
DOn't quite remember and I'm to lazy to search for it but I do know that todays CPU's doesn't need it.
