Rachpoil Posted August 25, 2010 Share Posted August 25, 2010 (edited) You seem to have a DirectX related error. What is the video card you are using. Some on board (integrated to the motherboard and mostly the Intel and VIA one) do not support all the features of DirectX that game use. Like lighting and shadow effects. You can try reinstalling DirectX from your GTA IV disk but if your video card is not 100% DirectX 9c or higher compliant, it will not solve your problem. --------------------------------------------------------- Sorry, i did not noticed that you had specify your 9800GT video card. No worry, you card fully support the DirectX requirements for GTA IV. In that case, try reinstalling DirectX from your GTA IV disk or you can download it from Microsoft: DirectX Edited August 25, 2010 by Rachpoil Link to comment https://gtaforums.com/topic/457735-gta-4-dd3d50-error-help-me/#findComment-1060098833 Share on other sites More sharing options...
mystk Posted August 26, 2010 Share Posted August 26, 2010 Either that or your PC is still using whatever inbuilt graphics the motherboard has which doesn't have IV's requirements and you're getting the error. Are you sure you set your BIOS to use the 9800GT? Link to comment https://gtaforums.com/topic/457735-gta-4-dd3d50-error-help-me/#findComment-1060099131 Share on other sites More sharing options...
link07 Posted August 26, 2010 Share Posted August 26, 2010 My old PC ran a similar setup but a different graphics card. I had trouble getting it to run. You can try uninstalling any previous .NET framework 2.0 and 3.0 (patch). Reinstall .NET framework 3.0 SP1 (or newer) Reinstall DirectX 9.0c You can patch the game afterwards.

mystk Posted August 26, 2010 Share Posted August 26, 2010 I'm 99.9% sure that your PC is still set to use whatever inbuilt graphics your motherboard has since the 9800GT supports SM3.0.

SNAKE DOC Posted August 26, 2010 Share Posted August 26, 2010 Reinstall video drivers. Use Driver Sweeper in safe-mode to completely remove them. Download and install latest drivers (or driver 196.21, as they are know to be VERY stable and gives great performance in IV.)

mkey82 Posted August 27, 2010 Share Posted August 27, 2010 Look at the back of your PC, where is the cable coming from your monitor connected? If the connector is higher among the other USB and whatnot connectors, then you're using the inbuilt graphics device on the mobo, as warlord. suggests. There should be another graphics card connector below, placed horizontally for your discrete GPU.
