how do i adjust the vram?

[ruthlessbiatch]

I am in a pickle here....I have a toshiba satellite L675D-7040.  I play WoW and i am sometimes having issues w/graphics....Is there anyway I can adjust my vram to improve gaming performance?
I have an AMD turion II Dual core processor 2.4 ghz, windows 7 64 bit OS,4gb ram,ATI radeon mobility hd 4200 series with 256 mb dedicated and 1661 mb shared  with 0 system memory dedicated.
How can i adjust these settings? I can't access any options to do so in my BIOS.  Your input is greatly appreciated....

Hello,

Your system specs are more than good enough to play WoW and all of its expansions.

Try the following to speed up your laptop…
1, Download and install the latest graphics drivers for your PC. The link is below for your specific model.

2, Download and Install the free “Game Booster” software

3, Run the Game Booster software you just installed and then run WoW

It should run smoother now
