Ok on va etre clair au sujet de Direct x9 Ex (L):
For those of you still reading, and interested in the facts, here they are:
- DirectX 9.0L was the early name designation for what is now called "DirectX 9.0Ex".
- DirectX 9.0Ex is a Windows Vista only feature. In a nutshell, it is DirectX 9.0c, with some modifications to work smoothly with the new driver characteristics of Windows Vista, which is significantly different at the graphics level than Windows XP. You can read more about DirectX 9.0Ex and how it fits into the Windows Vista picture here
- Windows XP cannot run DirectX 10 (technically, Direct3D 10) applications because of the significant changes in the graphics API and driver model
- And while I’m on it, the Xbox 360 cannot run Direct3D 10 because it lacks the Shader Model 4.0 hardware.
So, if you’ve read this far and STILL want Windows XP to run DirectX 10, you know the only answer: You’ll need to upgrade to Windows Vista and install a Shader Model 4.0 graphics card!
En plus court c´est DirectX 9.0c, avec quelques modifications pour fonctionner facilement avec les nouvelles caractéristiques de conducteur de Windows Vista, qui est sensiblement différent aux graphiques de niveau de Windows XP.
