EXTREME lag when running game on £2000 machine?

Hey guys, today I've literally been through hell trying to get this game working on my MacBook Pro.

I've basically gone out & bought Windows 8, created a partition on my hardrive (of my MacBook Pro) & installed it into that partition using Apples 'Bootcamp assistant'. After installing the operating system I also loaded the drivers which were given to me by Apples 'Bootcamp assistant'.

I now have the game on the Windows 8 (on my MacBook) which is a £2000 machine... I have got to the menu & experienced extreme lag to the point where I've even managed to turn down all my video settings & it is still lagging a lot despite my high-end computer hardware - here is my computer http://store.apple.c...B/A&step=config#

I have tried running the game on this website http://www.systemrequirementslab.com & everything is great but it says I don't have the required 512MB of video RAM... It says I have 256MB. This is complete bullshit? I believe I have 2GB of GDDR5 video RAM. It also says that my graphics card is called 'Microsoft Basic Display Adapter'. So I believe this is where the issue lies. My theory is for some reason one of the drivers which I have installed which was given to me by the Bootcamp assistant is messing with me.

This is literally all the information I can possibly provide, does anybody know how I could fix this?

Thanks you!

I see Minimum requirements for CPU is 2.8GHz And you only Have 2.3GHz. That might be a problem.

There's not a problem with my actual hardware. The minimum requirements is actually 2.0Ghz, were looking at the recommended requirements. I also made this mistake, I read '2.3Ghz & 2.8Ghz' & made my assumption. It says there that my CPU performs at 5.29Ghz & it scores in the top 84th percentile for CPU's tested. This can't be the issue!

looks a lot like your windows install hasn't correctly identified your GPU

also did you install directX?

in arma 2 or OA you should also probably try these settings (generally go high not low) which normally fix our new guys up after they install.

Managed to get it working, it's just one problem after another now. My server list isn't showing -.-

you're not alone there try using direct connect to a known server
