DD3D50 Error


Senatov

Recommended Posts

I previously had GTA IV installed and working/running perfectly with high quality/fps on my Mac as a Virtual Machine. I had it running on Windows XP. I recently switched to Windows 7 (Big Mistake) and I had to reinstall GTA IV. It installed perfectly and all I had to do was select for it to run in compatibility mode for Windows XP SP 3 (running in XP SP2 mode gave me the RMN40 error) The only problem is that now it comes up with a black DOS command box and the DD3D50 error upon launch. I know this means that Pixel Shader 3.0 and Direct X 9 aren't working with my Video Card. I am running 1TB of Hard Drive, 2GB of RAM, 2.4 GHZ processor, and Intel GMA X3100 Video Card. According to Intel, the X3100 runs Pixel Shader 4.0 and Direct X 10, but is also compatible with Direct X 9/ Pixel Shader 3.0. How do I fix this? How do I make GTA IV recognize that it can work? Don't tell me that I need to upgrade my equipment because GTA IV ran perfectly before on the same system.

Have you tried running it NOT in compatibility mode? I have Widnows 7 and run the game without using compatibility mode and have no problems.

Compatibility mode or not, it does the same thing, but I noticed under closer observation that the black DOS box will sit there for about 30 seconds, and then enlarge by itself to full screen, making the whole screen black as if the game is about to launch, but then go back to the DOS window and then the DD3D50 message comes up.

I just installed patch 7 and the black DOS box went away, and now it has me sign into RGSC before playing. After signing in the screen turns black as if it is starting up, but it then closes and gives me a different message. Instead of GTA IV Fatal Error DD3D50 it now says GTA IV Fatal Error DD3D50 - Pixel Shader 3.0 Required. My video card supports Pixel Shader 4.0 and Direct X 10, which I would assume to mean that it can also work with 3.0 and Direct X 9 which was installed as a part of patch 7. GTA IV worked just fine before with the same hardware. How do I get it to work? What version of Pixel Shader does it think I have?

I'm just going to get a new system soon and hopefully it should work then. Thanks for the help anyway.

Intel GMA X3100 Video Card.

 

That is not a supported video card by the game-according to the box the game came in, IV REQUIRES at least an Nvidia 7900 or better OR ATI Radeon x1900 or better with at least 256mb vram. The Intel video cards are shared vram, so, not all the vram will go to the game. That was the same error I got on my XP Pro PC with a Intel Core 2 Duo(Centrino) @ 2.0GHZ, 2GB Ram SP3 and an Intel GMA card.

 

If you would have read the Pinned "can I run it..." topic OR the box the game came in, you would have seen that your video card does not meet minimum requirements. Just a friendly heads up. icon14.gif

 

Also, if you downgraded to Windows XP, it is more than likely an illegal version, since according to Microsoft.com, XP stopped being sold on October 22, 2010. Here is the source straight from Microsoft:

We know you love Windows XP, and you're in good company. Millions of Windows XP users are fans of the operating system, and many depend on Windows XP to run earlier applications and hardware that is not compatible with Windows 7. Windows 7 is designed to be compatible with the most popular hardware and software products you use every day and even though we are ending the sale of Windows XP on October 22, 2010, we still plan to provide support for Windows XP until April 2014. Our Microsoft Support Lifecycle explains it all.

 

Notice it says "..We are ending the sale of Windows XP on October 22, 2010..." Because of that statement, I take it you have an illegal version.?
