no draw. in order to support gles2 sensible we made the engine core all the same code. so since to support gles2 we need to be entirely shader-only - we do the same for "desktop gl". doing otherwise will increase the codebase significantly and be a lot of work to support. so there isn't a "well you lose a feature by not having shaders". you lose the entire gl enigne. > > > Hi, > > > > > > For me E18/evas says my system does not support OpenGL or Evas has no > > > OpenGL support. > > > I have both a i915GM and i855GM system with glxinfo as attached. > > > Same compile flags are being used on both for efl/e18. > > > > > > Why is OpenGL not being seen/used on the i855GM (compositing is rather > > > slow when done by CPU)? > > > > > > If some features are missing, isn't it possible to just disable > > > corresponding visual effects? > > > > > > Bruno > > > > > > The different between the two: > > > --- /tmp/glxinfo-i915GM 2013-12-16 19:59:45.476169559 +0100 > > > +++ /tmp/glxinfo-i855GM 2013-12-16 19:59:44.186141694 +0100 > > > @@ -14,9 +14,9 @@ client glx vendor string: Mesa Project a > > > client glx version string: 1.4 > > > client glx extensions: > > > GLX_ARB_create_context, GLX_ARB_create_context_profile, > > > -
