OpenGL shader capabilities of Radeon HD 3870 are not detected on Windows 8.1

[Manuel Ullmann]

On Windows 8.1 with the latest Legacy Catalyst driver (13.1) the shader capabilities of my Radeon HD 3870 are not detected. 0ad falls back to the fixed render path. After that it does not detect an OpenGL extension. I'll copy the error messages, when I get home today. My Radeon HD 3200 IGP in my laptop is detected fine on Debian wheezy, but the drivers are too old for running 0ad in a playable manner.

I am surprised that 0ad shall run on Intel IGPs, especially on Windows, because the driver situation is like this (Vendor C, driver #2): ​http://richg42.blogspot.de/2014/05/the-truth-on-opengl-driver-quality.html So it should run better with Vendor B.

I will soon rebuild my computer and get an Intel IGP (Haswell). I guess, I will see how it runs, but actually I could still use the Radeon HD 3870, if 0ad manages to use it.

This is strange indeed. According to wikipedia your GPU supports OpenGL 3.3. Please see ReportingErrors and attach your system_info.txt.

Information about my system

Attached system_info.txt. Turns out, that the Catalyst installer was the culprit. It installed an OpenGL 1.1 driver. ;-) Using the device manager I could switch from 3870 WDM driver to 3800 series driver, which has the extension support. There is also a blog post about that. 0 A. D. is now up and running, however I have no sound. On my Laptop on Windows 7 the game crashed immediately, but I won't use it for gaming anyway.
