Wine detect and use only opengl 2.1
How did you come to that conclusion? Do you have a test program? The reason I ask is that you're wrong. Wine supports OpenGL 3.2 core profiles since 1.7.34. Of course, it's always possible that there's a bug, but you'd have to identify something specific that's failing to work. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=38158 --- Comment #3 from Ken Thomases <ken(a)codeweavers.com> --- You could have been clearer. I gather that you ran the glewinfo.exe program from <https://sourceforge.net/projects/glew/files/glew/1.12.0/glew-1.12.0-win32.zip/download>. What about that output is different from what you expect? Is this the problem:
OpenGL version 2.1 NVIDIA-10.0.19 310.90.10.05b12 is supported
?
From a +wgl log, it looks like glewinfo.exe/GLEW is just calling wglCreateContext(). It's not calling wglCreateContextAttribsARB(), let alone specifying any attributes.
When an app calls wglCreateContext(), the implementation may return a context of any version that is backward-compatible with OpenGL 1.0. As per the WGL_ARB_create_context spec, that can include versions up through 3.0, version 3.1 with GL_ARB_compatibility, or version 3.2 (or later) compatibility profile. OS X does not provide GL_ARB_compatibility, so 3.1 is not acceptable. Likewise, it does not provide compatibility profiles for 3.2 or later. It only provides core profiles. In fact, they are the more restrictive forward-compatible core profiles. On OS X, an app can only obtain a 3.2 core profile if it calls wglCreateContextAttribsARB() and specifies version 3.2, 3.3, 4.0, or 4.1; WGL_CONTEXT_FLAGS_ARB == WGL_CONTEXT_FORWARD_COMPATIBLE_BIT_ARB; and WGL_CONTEXT_PROFILE_MASK_ARB == WGL_CONTEXT_CORE_PROFILE_BIT_ARB. glewinfo.exe does not do that, so it just gets a 2.1 context. Was glewinfo.exe the real thing you wanted working? -- Do not reply to this email, post in Bugzilla using the above URL to reply.

I'm afraid there's no help to be had. With OpenGL 3.1 and later, the version number is not enough information. There are different "flavors" of OpenGL. Just because your card "supports opengl 3.1 and 3.2 features" doesn't mean that a game that wants "OpenGL 3.1+" can be satisfied. The game presumably needs the "compatibility" flavor of OpenGL 3.1. MacOS doesn't provide that flavor, it only provides the "core" flavor. A game would have to specifically look for the core flavor in order to get it. Your game is not prepared to work with the core flavor of OpenGL 3.1+. So, it can't work on MacOS and there's nothing that Wine can do about that. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
