    This library is not what people think it is. The library allows Windows developers to create 3D applications using OpenGL-DirectX interop. Normally developers don't get access to stereo3d support...
  2. Someone wrote a pulseaudio backend for the new...

    Someone wrote a pulseaudio backend for the new audio subsystem, but it hasn't been added yet. There are some concerns including maintenance. Anyway the new audio subsystem should handle pulseaudio...
  3. The Wine audio stack has been rewritten in Wine...

    The Wine audio stack has been rewritten in Wine 1.4. Internally it works similar to the Vista/Win7 audio service which is a bit like Pulseaudio. Wine has small drivers for relevant audio systems like...
  4. There are small differences between HLSL and...

    There are small differences between HLSL and OpenGL shaders which require some 'fixups' when the shaders are being used. I don't remember the exact details, may be some cheating is useful. Note a lot...

    Let me clear up the need for the shader compiler. Most games require DirectX runtime dlls (d3dx9_*.dll) which contain utility functions and the shader compiler. Some games install them while in other...

    I understand the motivation behind the new extension (syncing is tricky in certain applications), but I'm not sure if this GLX extension is really needed though. Plain old glFlush in multithreaded...

    Optimus support will likely never come to the blob. Essentially it would require Nvidia to integrate an Intel driver into the blob. Since the way Optimus works is that the Nvidia GPU does all its...

    Wine won't ship with DOSBox at all. Basically what this is all about is that when Wine encounters a DOS executable it will do 'dosbox appname.exe' (in a slightly smarter way). It is all about...
  9. Like Windows the file format used on DOS was a...

    Like Windows the file format used on DOS was a .exe (and the same for .NET). This just allows Wine to offload the handling of DOS executables to DOSBox if we encounter a DOS application. We have DOS...

    Really make sure that both drivers are running the GPU at the same clock speeds else especially on the 8600GT / 8800GT you may be comparing apples to oranges.
  11. The OpenGL performance in Wine CAN be identical...

    The OpenGL performance in Wine CAN be identical to Windows under certain circumstances, but by default not in all cases. Our OpenGL code contains locking code around each function call (needed for...

    Typically in virtualization software, the guest operates on 'virtual CPU cores'. These virtual CPUs are (depending on the hypervisor) treated as threads which the hypervisor can schedule. Depending...

    Let me clarify the concern we have in Wine. There is nothing illegal essentially with writing a Direct3D11 to 'something' wrapper where the something is OpenGL, Gallium3d or any other API. The...

    For a big part this is a SGI issue. At the OpenGL BOF (I was there) they mentioned that they (Khronos) were finally working on a OpenGL 4.1 conformance test suite. The old test suite was from OpenGL...

    The d3dx9_* dlls are utility dlls which can optionally be used by games. Among functionality this contains a shader compiler/assembler, functions create e.g. a texture from a jpg file and so on.

    When you encounter regressions perform a regression test and we will try to fix them. A change which improves app A, B and C can cause a regression for app X. It can mean that the change is wrong but...

    Regarding 2D performance, you should try it with the Direct2D acceleration settings as right now you are comparing hw xrender vs software.

    We are just forwarding all opengl32 calls to libGL. This just updates opengl32 with OpenGL 3.3/4.0 support. Your libGL needs to offer that for it to do anything.

    These days most work is going on in >=D3D8. The people who work on this area are typically employed to do so. So now and then someone wants to get his favorite oldie working well and we support him...

    If any benchmarking is in fact done. It is also important to try the same games/apps using WineD3D on Windows to get an idea of how good/bad the emulation code in Wine is since the drivers are the...
