It says "as delivered with Windows 2000 or Windows XP". That means it wants features that comes with Windows 2000 or Windows XP. "Client GLX version string" does not say much. The way GLX works, is that there's a "client" (the GL library that applications link to), and there's a "server" (the X server). Both must support the desired features. Normally the problem is the server support. The standard WGL features found under Windows correspond roughly to GLX version 1.3. The "OpenGL version string" (or the more fine-grained "OpenGL extensions") is yet another detail to worry about, of course, as this relates to the actual hardware features that an application can use. This is probably less critical than the server GLX version string, though. Let's compare OpenGL with a Linux desktop: The "OpenGL version string" is the version of the distro. The "OpenGL extensions" is the individual applications available to the user (and typically, as you add more apps, a new version of the distro is released). The "client GLX version" is the system libraries (like libc6). The "server GLX version" is the OS kernel. Now, compared to GLX 1.2, GLX 1.3 is an almost complete redesign (and far more in line with Windows functionality); let's consider GLX 1.2 the equivalent of a kernel with OSS audio, and GLX 1.3 the equivalent of a kernel with ALSA audio. If you somehow decide to run version 1.2 of the Linux kernel, then is it then an xmms bug that you can't configure it to use the ALSA dmix plugin and get 5.1 surround sound? Your hardware may support surround sound. Doesn't matter if your kernel doesn't even support ALSA, does it? Sadly, the open source OpenGL drivers have a "kernel" that don't implement GLX 1.3. Implementing GLX 1.3, like implementing ALSA, doesn't require any special hardware features, it's purely a software issue. But it's a software issue in the *drivers*. Not in Wine. _______________________________________________ wine-users mailing list wine-users@xxxxxxxxxx http://www.winehq.org/mailman/listinfo/wine-users
