Description (last modified by misha) (diff)
Host: Windows 7 Ultimate 64-bit Guest: Windows XP Professional SP3 32-bit 3D acceleration: Enabled
The Windows XP guest reports the OpenGL version as "2.1 Chromium 1.9". However not all OpenGL features up until OpenGL 2.1 are supported. The following OpenGL 1.5 functions are missing: glBeginQuery, glDeleteQueries, glEndQuery, glGenQueries, glGetQueryObjectiv, glGetQueryObjectuiv, glGetQueryiv, glIsQuery. This means that OpenGL programs that expect full OpenGL 2.1 support may crash if it uses the OpenGL version string to determine whether or not it can use OpenGL 1.5 occlusion queries.
Attached is output from glewinfo which lists extensions that are present/missing.
