Hello, I'm having very strange problem with 3D. Not only games, but all 3D programs (i have 8800 GT video card). I've tried installing drivers from nVidia's site (169.27 was the latest, if I remember correctly). Installation was successful, after restart I see my display adapter is detected correctly and i can set up appropriate screen resolution. But the thing is, if I go to nVidia Control Panel while in XP 32 bit, it doesn't even show spinning 3D logo in the Preview section of 3D Properties Category (but it should, the area just remains empty). Basically, I cannot run any DirectX 3D App/Game. BUT! If I run > dxdiag and preform different D3D tests from there all work very well. Yes, I have latest Direct X installed (directx_mar2008_redist). 3D Max cannot locate d3dx9_34.dll (even if I copy it to system32 folder, it lunches, but viewports do not work in direct 3d mode). So by some mysterious reason, I cannot run any program that works with Direct3D (even nVidia's control panel). However, under Vista 32 bit (only after refreshing the system's rating information and having all the same drivers installed before that refresh, all works ok). The thing is I can't use Vista with VMWare, that's why I need XP up and running with DirectX support. If anyone could suggest something, I would be very thankful! Thanks in advance!
