What game? You have Intel Graphics, which if you update the graphics drivers might just support ubyte4n (OpenGL 2.1) vertex data; but if you're running something more sophisticated than Peggle (say, Far Cry) you would want a recent vintage of ATI videocard as no doubt mentioned in the install text and on the game's front matter (box, Steam news, etc.) as well. You get one PCI x16 slot to put such a card in; no SLI (but then the cost stays helpfully under $200.)

SOURCE: on COD4 I keep on getting this problem: UBYTE4N vertex data.

Simply put it means your Video card is not up to the min standards to play this game.
Do you know what video card is in your PC?
Is it a laptop or desktop?

COD4 needs 100% compatible DirectX 9.0c card with at least 128mb of ram.
Yours I'm afraid doesn't appear to be.

As the game is initializing it checks for the basic requirements to run, as you can see as it reaches the direct 9 interface it seems to except your pixel shader version but can't find transform and lighting (vertex shader) which it needs in order to run, so hence comes up with the error.
You may have to upgrade to DirectX 9c if it will allow you to do so, if not:

The chances are you have an older PC with an older video card (which could possibly be changed and upgraded), or you have a PC with an integrated card (which could also be upgraded) or a laptop with integrated graphics (which will almost be impossible to upgrade)
Although there are some amazing laptops on the market, they are not generally that good at playing high spec modern games, simply put because they are compact, they do not have the room to use the large high powered video cards necessary to do so.

come back with a few more details
hope this helps
Cheers
Bri

UBYTE4N vertex data doesn't support my computer


Try updating your video card drivers to the latest ones and also update to the latest version of directx.

If you do those two things and call of duty 4 still wont' run then that means the video card doesn't support the game.

World at war problems UBYTE4N vertex data


Hi,

Many computers do not come with a dedicated graphics card, which Call of Duty will require. If you don't have a dedicated graphics card installed, there is no way to play a game that requires it.

The good news is that most computers can be easily upgraded with a new graphics card, and you can play more advanced games. For more information about what would be compatible with your system, you might want to call the Upgrades or Tech Support department of the company that made your computer, or post more detailed information about it here and we can post a walkthrough.

UBYTE4N vertex data COD5: for the computer not working! plz help


You sound like you are on top of things, but I will give you some tasks to do first.

Since I have no idea on what all you have done, I have some questions / suggestions.
1st: Have you Defragmented your computer? If not this month, please do so ASAP.
2nd: How much free space is left on your hard drive? You need over 15% free space.
3rd: Have you cleaned out you cookies, temp Files & Temp. Internet Files?
4th: Every item you add or install anything on your computer, it starts running each time you boot up.
This eats up your limited power and processor.To see this you will need to use the CRTL/ALT/DELETE keys to open up your TASK MANAGER
On the right side you will see a TAB called START UP. Each item that is checked or ********** is running in the background.
You do not need this stuff running. Its a gift of Microsoft to make it start faster for you and is no longer a needed item since you have so much power.
Uncheck most if not all items, like MSN or YAHOO chat, Games and anything not directly related to the computer operation.
Please keep me informed.
