Note that imposing an OpenGL version in this manner creates a strong constraint I imagine you know what you’re doing though -). Or glutInitContextProfile(GLUT_CORE_PROFILE) Īlong with the version using glutInitContext(). If you want a newer version of OpenGL, you need to specify the corresponding profile: glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE) Mesa will give you an OpenGL 3.0 context (this sort of makes sense since profiles were introduced in OpenGL 3.0, so that’s the last version where applications can be expected not to know about them). If you don’t specify a core profile when creating your context, or if you write something like glfwOpenWindowHint(GLFW_OPENGL_PROFILE, 0) So basically, why does Mesa say that the core version is 4.5, but then gives the version string of 3.0? (The same version glGetString(GL_VERSION) returns.) And how can I regain access to OpenGL 4.4? (If not 4.5!)Īs I understand it, the important value is the “max core profile version”, not the “OpenGL version string”. I am certain that my hardware supports up to OpenGL 4.4, as this machine was previously a Windows 10 machine before MS pushed/forced a broken update, and I developed using OpenGL 4.4 and GLSL 440 during that time.Īdditionally, I can run OpenGL 4.4 programs on Java through JOGL, which has all the required OpenGL libraries packaged together and doesn't seem to rely on the system version at all.
