Secret of Graphics in Windows Vista - Directx 10:
Windows Vista had been loved due its excellent real time graphics.But
have you ever thought what makes those graphics real ? Thanks to
DirectX 10 which is making thses ultra high real time graphics
real.Before I dig into Directx 10.Lets get to know little about it.What
is Directx ?
Directx is the core which makes the games work.All the graphics designs
which you even cant imagine in real time, is possible due to it.When
Microsoft launched its operating system in 95 it was quite unfriendly
do ue to internal restriction on hardware like audio device video cards
and other peripherals.Thus directx made a set of api or functions that
can be used in windows.The main advantge was taken by games which had
much more freedom
How DX10 makes it so real ?
1. In real world every point is uinque.Even 2 points on your face is
not similar.When Dx stared initially due to restriction on hardware and
development part it was restricted on number of unique objects that can
show in Scene.But with DX10 you can show hundreds of unique
objects.This means if you have to show 100 flowers in a field you need
not to create one and copy it to 100 but create 100 different one.That
makes it more real.
2. Displacement Mappings one more technique that makes Humans showing
in most of the hi-fi video games so real.More details texture you have
much real the image will look.DX10 has something called as geometry
shaders.By adding more “triangles” in a particular point it makes them
real.
Now think of those graphics u see on your vista’s desktop.Thats what DX10 making it happen
Comparison of DX 9.0 and DX 10
Lets take a look at the images below and You will need no words to say how much they differ:

Can it make my CPU slow and system crash.?
It can if you don’t have a separate Graphics card.The gae has gone when
the cpu had to all the work.If you have a separate graphics card DX10
will transfer the load on to it while your cpu can still do other
things like downloading email checking and browsing.
You can read these topics for DirectX 9L which is going to be DirectX10
for windows XP.I found it through google search DirectX 9.L will be a
DirectX 10 for Windows XP
So what does all that mean ?
Over all as the end user you might be more concerned about your system
performance.Thus u want to play hi-fi games without ur system crashing
down or getting ur screen blank.Keepin this in mind the benefits of
DX10 with Windows Vista you might be compelled to upgrade seeing these
advantages, specially as a gamer u will.
