spent $200 to loose FPS ??

[Zyco187]

I just updated my system with new mobo and ram, and I ran the E08 misson on Arma 2 OA that is a benchmarking program not an actual misson, and I went from 46 FPS to 41. how is this possible. i have did some searching on tweaking the video setting in OA and did stuff like change the res and 3d to 720 and turn off vsync with that it gave me some FPS boost. then I ran the benchmark and got 47 FPS. today I upgraded my parts and with the same video settings i am only getting 41 FPS. is there somthing else I need to tweak like page file memory or something? or allocate more of the new 8gb ram with the OA program.

here is my old system.

I see only one bad thing = AsRock lol

But on serious note, if that is the only things you changed then its mobo. Vengeance memory cant be worse than your old memory.

[SANGUE-RUIM]

ive always used Asus mobos, they r gr8
i dont believe memory would have such impact on performance, so it must be ur new mobo

well, good luck

Is this a fresh installation of Windows 7, or did you use Acronis/Ghost etc to transfer over your existing OS installation?

It's because you have the same processor. ArmA relies so much on a good processor it's crazy. I stepped up from a FX-4100 @ 3.6 GHz which was giving me 30 fps every where on mid-high to a stock i7 3770k and got 60+ fps anywhere on all very high (and I even switched resolution from 1680x1050 to 1920x1080). Was using the same GTX 570 each time.

Also, yeah, what Priceline is saying, Intel has way better performance compared to AMD. AMD does the job, but Intel is way more efficient.

[LITOralis.nMd]

Priceline is correct, Arma2 engine is single threaded, which means you'll be bottlenecked by the processes per second (shorthanded as Ghz ) that your CPU can handle on a single core.

First, you can overclock your new MoBo, BUT, you will run into heat issues if you go for a higher overlcock, as it is only a 4+1 VRM. Here is info:(overclocking) AMD FX-8120 on Asrock 990FX extreme 3
Check the links in xd_1771's signature for basically all relevant info. Specifically this:
http://www.overclock.net/t/943109/about ... processors

You have 4+1 VRM, you could probably get to 3.5Ghz, maybe 3.6, a 30% increase in CPU speed.

Overclocking your CPU will result in an almost linear increase in Arma2 :O A FPS, so you'd be near 55 FPS at which point your GPU would be the bottleneck, i.e. you'll hit theoptimal sweet spot for your combined hardware.

Second, DO you use optimized command line options to start Arma2 :O A ? You can significantly increase Arma2 :O A performance by doing so. Specifically you need to add

-cpuCount=6 -maxMem=6144

For what it's worth, here are my launch parameters for ArmA 2:

-nosplash -cpuCount=8 -nopause -winxp -world=empty -exThreads=7

I've heard that if you have over 4 gigs of memory, it doesn't matter anyway if you include it in your parameters as ArmA doesn't utilize it correctly.
