Mustals Posted October 17, 2001 Share Posted October 17, 2001 Is there any way to fix a problem that has developed when testing Direct 3D from the DirectX diagnostic tool, it completes the first test OK but the second one produces the following error:- Direct3D test results: Failure at step 18 (CreateDevice): HRESULT = 0x88760091 (Invalid pixel format) This is on DirectX 8 Downloading 8a at present... 0 Quote Link to comment Share on other sites More sharing options...
Mal Elder Posted October 17, 2001 Share Posted October 17, 2001 What kind of video card is it? First thing after you get the DX update is to make sure you have the newest video drivers...thats probably where the issue will be, DX8a will probably give you the same error. DX is making a call to the drivers and getting the wrong information back. 0 Quote Link to comment Share on other sites More sharing options...
Strider Posted October 18, 2001 Share Posted October 18, 2001 If you're runing Win2k, have the latest nVida drivers, and DirectX8...your problem may be the same one I had. The latest drivers are not working in this environment. I had to backup to a previous vidod driver version to get 3D to work...still can't get the 3rd DirectX test concerning AGP to work...it's greyed out for me. Also, a couple of us ran tests on machines where I work...one machine had the same problem as mine, another worked just fine...both of those machines were Win2k Server. The one that worked ok, had a Vanta 4meg card (Intel 400 CPU), the other had a Vanta 8meg card (Intel 700 CPU)...mine is eVGA 32 meg card (AMD 800 CPU). All running the nVida drivers. 0 Quote Link to comment Share on other sites More sharing options...
Mustals Posted October 18, 2001 Author Share Posted October 18, 2001 Well it was a Rendition Verite card now its not, replaced it with a Voodoo 3 all fixed. Also have that greyed out button for Direct x 3d texture acceleration test.??? [ 10-18-2001: Message edited by: Mustals ] 0 Quote Link to comment Share on other sites More sharing options...
Mal Elder Posted October 18, 2001 Share Posted October 18, 2001 Thats wierd, they work great on my 2k box (: 2k Server is a poor platform for DX...it's not made to run games, so DX support is iffy in that area. Are these the 21.81 or 21.83 version of the drivers? 0 Quote Link to comment Share on other sites More sharing options...
Mal Elder Posted October 20, 2001 Share Posted October 20, 2001 Texture Acceleration is for AGP cards only, and as far as I know the Voodoo3 is a PCI card...if it is an AGP version, then it doesn't support Texture Acceleration as far as DX is concerned. Having it greyed out shouldn't matter, just means its not available...as long as the other sections work, you should be ok. 0 Quote Link to comment Share on other sites More sharing options...
