A couple of days ago I bought the Asus AH3650 Silent AGP video card. This is the most recent AGP Radeon type card I could get hold of.
The problem is that even if DirectX works fine, I can't use OpenGL applications. OGL query tools identify the video renderer as 'GDI generic' and card's vendor as "Microsoft Corporation" which is very bad. To experiment I installed Windows XP (SP2) on a new partition a couple of times, downloaded some older Asus drivers, tried to install the most recent AMD drivers - nothing worked so far. OpenGL games don't work.
But depending on the driver supplier, the results differ. AMD drivers usually make OGL apps crash either producing exceptions or "Context creation errors" (don't know what that means though).
I have a Pentium IV 2.66 GHz processor, 2 GB RAM, my primary OS is Windows XP (SP3).
If you have any idea what I can do in this situation, please don't keep it a secret.
