[Bug 47011] New: SampleCount registry key ignored for OpenGL rendering in early Unreal Engine games

https://bugs.winehq.org/show_bug.cgi?id=47011

Bug ID: 47011
           Summary: SampleCount registry key ignored for OpenGL rendering
                    in early Unreal Engine games
           Product: Wine
           Version: 4.5
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: opengl
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

The SampleCount option is very useful for applying anti-aliasing to older games
and works great for DirectX 7/8/9 titles.

However, when using OpenGL the SampleCount option seems to be ignored.

Games Tested: Unreal Tournament (1999) and Unreal Tournament 2004. When using
Direct3d rendering the performance is poor but SampleCount works, when using
OpenGL rendering the performance is far better but the SampleCount option is
ignored.

I'm not sure if this affects all OpenGL games but I'd imagine it's the same for
any games that use OpenGL rendering.

Yes, the SampleCount option overrides the sample count for Direct3D swapchains.
This option isn't expected to work for OpenGL games.

would it be possible to enable this for OpenGL as well?

I guess we could add a similar hack to WGL. I think it's going to be quite a
bit more convoluted than the d3d version though.
