Maybe he meant WebGL, but even then it could be done very well as with more modern OpenGL variants with bitmapped font tables. OpenGL on Mac is 3.2 IIRC. Nvidia recently tinkered with proprietary version of OpenVG with beautiful text rendering capabilities. There are numerous ways to make great text with OpenGL be performant with native code. Even GUIs with IMGUI approach. Some of those techniques could be done with WebGL, I'm sure. So, I don't really understand his point about text and OpenGL a no go Sure, WebGL is not all you can get with native and OpenGL, but nowhere near a fiasco in performance.
