Conflict BTW DirectX9 and 10

[Guest]

Hey I bought a new laptop a couple of weeks ago, and this computer has the
window Vista by default! However I'm facing a lot of troubles with the games,
they are not working with DirectX 10, and if you install DirectX 9 the games
willl Crash! Do u hv any ideas what's going on?What can I do?

Well, understandable, you're confusing things a little.

DX10 is it's own install under Vista
DX9.0L is it's own install under Vista.
The two do not work together

You can't use DX10, if you don't have a DX10 video card. If you are using a
DX10 card, with Vista, but playing a DX9 game, then you are still not using
DX10. Only when you play a DX10 game, in which there are currently none
available, under Vista with a DX10 card will you be using DX10

Vista ships with DX9.0L so that it will be compatible with all the DX9.0
(and 8 and 7) games. Vista's Aero uses DX9.

If you're not able to play games, you might be missing some add-on files,
which you can get by applying the DX9.0c runtime updates

You might also have a video driver conflict, in which you'll need to see
what driver your laptop maker has available for you to update with.

What games are you having trouble with and what are the specs of your laptop
?

Well I have a Compaq Presarion Dual Core 1.6 window vista home edition
1 GB Ram
256MB VGA

For the games almost all the games:
Devil May Cry 3 special edition
Need for speed carbon
Prince of persia is working but with some image distortion
The new Red Alert 2007 Tiberium War, you start the game once you start
building a base, the game crash
and some other
Thx for your help

You didn't mention which video card you have. Also, can you tell me the
model number of your laptop.

Just so you know I played all of the GDI and Nod campaign of C&C3 under
Vista 64. So it should work

It's a Presarion C500
For the videa card it's Mobile intel(R) 945GM Express chipset controller WDDM
and I have Vista 32
thx

As you may or may not know, the C500 is the overall model number or series
number, on the bottom of the laptop it should have the exact model number
like the C502US.

But I don't think it matters too much as, most of them seem to use the same
graphics card. I will have to say, that's a terrible graphics card to get
stuck with and it's not a DX10 card, so you'll pretty much never be using
DX10 on that laptop.

Here is a Jan 07 driver for the card

Note that alot of people have problems with the newer games and the Intel
Graphics card. It's not very powerful. Here's a review of the card
