Getting The Most From Your Laptop Video Card
Getting
more from your laptop video card can involve..
Drivers Make sure
you have the latest drivers installed
Application Suites Get more from
your graphics card
Hardware acceleration settings
Make sure hardware acceleration is up to the max
Minor Tweaks what else can we do
to eek out a bit more performance?
The laptop video card is perhaps the weakest link in most
laptops, as such we get asked many times if video cards in
laptop can be upgraded, 99% of the time the answer is no
unfortunately, this is due to laptop video cards either being
part of the motherboard or the shape has been specifically
designed and there simply is nothing around that will physically
fit.
But that is not the end of it; there is however a number of
tweak and tips can give a performance boost to most types of
laptop graphics card.
Always make sure you are using the latest
laptop video card drivers, manufacturers and developers tweak
their software drivers making the code more efficient with each
software revision.
Do not just install the driver on its own,
one of the biggest mistakes people make when upgrading video
card drivers is just upgrading the laptop video card driver.
Most manufacturers provide complete management suites too which
should also be upgraded, these provide extra settings for
features for Open GL or other hardware throttling
Laptop graphics card memory
If you laptop has dedicated memory
then the chances are you will probably not be able to increase
it, but saying that its worth checking as some do accept plug-in
type modules.
The other type of laptop video card
memory is the shared memory type, which generally offers less in
the way of graphics ability than the dedicated type, with shared
memory types you can increase and decrease the amount of video
card RAM as it is shared with the main system RAM, so if you
allocated 512mb to the video then thats 512mb that the system
will lose, the best option here is to upgrade the laptops RAM so
you can allocate the maximum amount of RAM to the laptop
graphics card with minimal impact to the overall system RAM,
this is either done though the graphic card/manufacturers
software or the BIOS.
Many later laptops have dynamic
video memory allocation which allocates memory on demand
depending on video usage; even in this case increasing system
RAM will give performance gains as more memory can be allocated
to the video with lower cost to the systems resources.
Hardware acceleration
Within Windows, right click on the Desktop and select
Properties Settings Troubleshoot this will
present the Hardware acceleration section the slider
should be set to Full unless & Enable write combining should be
ticked if you encounter any issues you can switch this off
and trim back the Hardware acceleration slider.
Note just enabling write combining can in
effect double the graphics performance by combining multiple
writes to single operations which most modern video cards
support.

More
minor tweaks
To increase the performance further free up
as many system resources as possible, this means only run
applications that you are using.
Lower the color depth from Highest 32 bit, to
Medium 16 bit check the difference in the look of images
differences will be small if any. To do this right click on
the desktop Properties Settings Color Quality
All the extra flashy Windows display
options come at a price, disable these and setting your system
to performance is another easy tweak.
Start menu Control Panel
System -Advanced tab under Performance choose Settings
now you have 4 options
Let Windows Choose
this will generally switch everything on
Adjust for best appearance
- but lowest performance as it switches everything on
Adjust for best performance
No messing disables all unnecessary graphic options for maximum
graphic performance
Custom If you
want to keep some of the XP look select the bottom 2, Use drop
shadows and Use visual styles.
