performance tweaking for laptop - tips

If anyone else, like me, has an intel GMA950 video card on their laptop.. they are probably having a bit of trouble getting it to run SC2 smoothly, well here are some tips!
-low resolution with widescreen aspect ratio!
If your like me then you set your resolution down to the lowest the game allowed 1024X768 ... one big problem - thats a 4:3 aspect ratio! which totally suck because you want to play widescreen but with low resolution.
THE SOLUTION is to open your starcraft2 variables text file and punch in some custom resolution numbers!
I found my variable file @ C:\Users\USERNAME\Documents\StarCraft II
there are 2 lines that you need to edit
height=768
&
width=1024
my native screen resolution is 1280x800 which is a 16x10 aspect ratio so I started up my calculator and punched some numbers and came up with
height=640
&
width=1024
another option would be
height=768
&
width=1228
both of those options are LOW RESOLUTION and WIDESCREEN ASPECT RATIO

-upgrade to windows 7 already!
When I had windows xp my video card driver would only allocate up to 128mb of video memory. After upgrading to windows 7 you will notice that your gma950 will now allocate up to 768mb of video memory! its not a huge performance boost but it can definitely help with loading times and parts of the game where there are a lot of units on the screen.
intel halted development of the windows xp gma950 driver a while back. the windows 7/vista drivers have more features and are still being updated. I dont remember the specifics but the windows 7 driver now includes features that the xp driver doesn't have!

Turning down your sound options helps as well. for instance change it to mono, 20 channels, reverb off, and turn off the music and effects (if you keep the interface sounds and unit response sounds on it still feels like you have enough sound it the game to play without noticing anything missing) just turn on your ipod and listen to your own music. Also I noticed that if you go down to 16 channels then you start missing out on alerts and certain sound effects, so at minimum I would recommend 20 channels
