can you do its will support.....

how can i do my I7 920 will be 100% use when i play ARMA2

like Exploit the CPU

Ur question is way to technical for me ;)

Do you mean...how do u know ur I7 920 will be 100% utilized by the game?

Or Will it use 100% of my CPU

Best answer try it

I think the supports 4 cores max

I believe the Core i7 CPUs are best used with the cpucount switch. Just add -cpucount=4 to your Arma2 link in the target line. For example:

"C:\Program Files\Arma2\arma2.exe" -cpucount=4

Try with/without HT, some games/apps works better with HT on, others with HT off (some has no effect). As far as i know the only way to turn HT on/off is in the BIOS.

Edit: HT = Hyper Threading. For those that dont know what it is :)

Is that HT thing only relevant to i7 or quads in general or should i do it with my dual core also? Think i missed that discussion...

As far as i know the only processors that has HT is Pentium4, Atom and i7.

The Core family (Core2Duo/Core2Quad) does not.

You can't - You cannot control the game's CPU usage directly. You could theoretically design a mission in the editor that would use 100% of your CPU, the problem being that it would probably run exceptionally badly as you are leaving yourself with no CPU overhead.

Yep, the Core2Duo/quad doesn't support HyperThreading. Honestly, there is currently not many reasons to leave HT on with the i7's and good reason to disable it.

HT basically creates virtual cores so if you have 4 cores then HT will make it into 8 cores. In many cases this is good, but in a lot of cases it can cause cache thrashing. Basically what that means is that if playing a game and you note that either your cpu keeps spiking in the performance monitor, or your games fps keep spiking, then you're likely to be suffering from cache thrashing and turning off HT should increse performance.

The alternate to turning off HT is to use the -cpucount=4 switch. Basically it attempts to get Arma 2 to only use the 4 physical cores (as oppose to the virtual cores), the problem being that if any load on the system kicks in while Arma 2 is loading then there's a good chance that it'll use 1-2 virtual cores and 2-3 physical cores meaning that you'll still suffer from cache thrashing.

mm...I`m Understand =]

i will turn Off the HT

i think you are right

becuase i saw ppl with E7300 and 250GTS

on V.high sittings

thanks i will try
