<div dir="ltr"><div>Yes you perfectly sum up the situation. </div>Excepts the fp64 extensions, the REDWOOD cards supports as many OpenGL4+ extensions as the later cards (RadeonNI/SI), as you can see here: <a href="https://people.freedesktop.org/~imirkin/glxinfo/glxinfo.html">https://people.freedesktop.org/~imirkin/glxinfo/glxinfo.html</a> </div><div class="gmail_extra"> <div class="gmail_quote">2016-06-04 8:51 GMT+02:00 Constantine <<a href="mailto:Hi-Angel@yandex.ru" target="_blank">Hi-Angel@yandex.ru</a>>: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Wow, cool, I didn't even know it is possible! So, it is like that: $ MESA_GL_VERSION_OVERRIDE=4.1 glxinfo | grep version server glx version string: 1.4 client glx version string: 1.4 GLX version: 1.4 OpenGL core profile version string: 4.1 (Core Profile) Mesa 11.3.0-devel (git-329d115 2016-05-26 trusty-oibaf-ppa) OpenGL core profile shading language version string: 4.10 OpenGL version string: 4.1 (Core Profile) Mesa 11.3.0-devel (git-329d115 2016-05-26 trusty-oibaf-ppa) OpenGL shading language version string: 4.10 OpenGL ES profile version string: OpenGL ES 3.0 Mesa 11.3.0-devel (git-329d115 2016-05-26 trusty-oibaf-ppa) OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00 So, just to recap: the card hardware doesn't support some mandatory extensions — fp64 — thus staying at 3.3 version, but still have other — probably, most — extensions from 4.1. As apps does checking version, rather than extensions, there's a possibility that an app still would run, when version is faked. Thank you! Btw, just if anybody curious: Wine source I have doesn't seem to use GL_ARB_gpu_shader_fp64 anywhere except «opengl32» dll, so DX games, probably, should work just fine. <div class="HOEnZb"><div class="h5"> On Saturday 04 June 2016 14:03:03 Albert Freeman wrote: > If you are having trouble with using an application that wants OpenGL > 4.x then try faking it with mesa environment variables and hope that > the application does not use fp64 etc. > > On 30 May 2016 at 05:55, Benjamin Bellec <<a href="mailto:b.bellec@gmail.com">b.bellec@gmail.com</a>> wrote: > > Hi, > > > > The fact that the REDWOOD cards (your HD 5730M is a part of the REDWOOD > > family card) are OpenGL 4.4 compliant is not completely true.
