How to Fix UBYTE4N Vertex Data Error in Windows 7
If you are trying to play Call of Duty 4: Modern Warfare or other games on your Windows 7 PC, you may encounter an error message that says "Video card or driver doesn't support UBYTE4N vertex data". This error means that your video card or driver does not support a certain feature called vertex shader, which is required for some games to run properly. Vertex shader is a technology that can be found in most dedicated video cards, but not in integrated video cards (such as Intel).
Fortunately, there are some possible solutions to fix this error and play your games smoothly. Here are some methods you can try:
Method 1: Update your video card driver
One of the most common causes of this error is an outdated or incompatible video card driver. To update your driver, follow these steps:
Press Windows key + R to open the Run dialog box.
Type devmgmt.msc and click OK to open Device Manager.
Expand Display adapters and right-click on your video card.
Select Update driver software and choose Search automatically for updated driver software.
Follow the on-screen instructions to install the latest driver.
Restart your PC and try to play your game again.
Method 2: Use 3D Analyzer
If updating your driver does not work, you can try to use a software called 3D Analyzer, which can emulate some features of a dedicated video card on your integrated video card. This software may work with older games, but not with newer games that need Shader Model 3.0 or higher. To use 3D Analyzer, follow these steps:
Download 3D Analyzer from this link.[^1^]
Extract the zip file and run 3DAnalyze.exe.
Click on Select and browse for the game executable file (such as iw3sp.exe for Call of Duty 4).
Check the boxes for Emulate HW TnL caps and Force SW TnL.
Click on Run and enjoy your game.
Method 3: Contact Intel or your computer manufacturer
If none of the above methods work, then you might need to contact Intel or your computer manufacturer to know if your video card meets the minimum system requirements for the game you want to play. You can contact Intel here: http://communities.intel.com/community/tech.[^3^]
You can also check the system requirements for Call of Duty 4: Modern Warfare here: https://www.systemrequirementslab.com/cyri/requirements/call-of-duty-4-modern-warfare/10746.
If your video card does not meet the requirements, you may need to upgrade it or buy a new PC that can run the game smoothly.
