I implemented an orbit camera in my own OpenGL ES 2.0 application. I was getting extensive amount of flicker while rotating the camera using the mouse.

When I added the line eglSwapInterval( ..., 0.1); after eglSwapBuffers() and then the flicker immediately stopped. I am not able to understand why eglSwapInterval solves the flicker problem? (The FPS of my app prior to eglSwapInterval was around 700FPS)

(The flicker is NOT due to z-fighting because I have set near and far clip planes as 100 and 500)
