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 these 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 due 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 advantage was taken by games which had much more freedom

How DX10 makes it so real ?

1. In real world every point is unique.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

Can directx 10 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.
