Yes, I tried some days ago, and it seems to need more work with monogame 3.7 sources. Also it produces an opengl exception before to start to run even the iOS game template by default on visual studio… the opengl errorcode was 26… something, sorry, I can’t rebember the exact error number.
Thank you anyway, finally I made two shaders and does not seems to impact in the performance noticeably 
Should be nice to to find a path to implement OpenGL ES 3.0, stay on ES 2.0 noradays have no sense.
