Upgrading our basic window from the initial tutorial of the series with functions to create basic shaders in OpenGL and also playing around with the background color of the SDL window.

Just wondering if this series is going to be on using OpenGL or how to use it (graphically) to build a game

Do you ever run into issues where glSwapBuffers is slow, and where it may vary depending on the shader program you use? Im probably profiling wrong, but i see a range of 1 to 1.5 ms time when rendering about triangles per frame. Just curious.
